  • Error messages related to impossible subplot geometries are now much more helpful 2897

Fixed

  • px.scatter_geo support for text is fixed 2923
  • the x and y parameters of px.imshow are now used also in the case where an Image trace is used (for RGB data or with binary_string=True). However, only numerical values are accepted (while the Heatmap trace allows date or string values for x and y). 2761

[4.12.0] - 2020-10-23

Added

  • For add_trace, add_shape, add_annotation and add_layout_image, the row and/or col argument now also accept the string "all". row="all" adds the object to all the subplot rows and col="all" adds the object to all the subplot columns. (#2840)
  • Shapes that reference the plot axes in one dimension and the data in another dimension can be added with the new add_hline, add_vline, add_hrect, add_vrect functions, which also support the row="all" and col="all" arguments. (#2840)
  • The add_trace, add_shape, add_annotation, add_layout_image, add_hline, add_vline, add_hrect, add_vrect functions accept an argument exclude_empty_subplots which if True, only adds the object to subplots already containing traces or layout objects. This is useful in conjunction with the row="all" and col="all" arguments. (#2840)
  • For all go.Figure functions accepting a selector argument (e.g., select_traces), this argument can now also be a function which is passed each relevant graph object (in the case of select_traces, it is passed every trace in the figure). For graph objects where this function returns true, the graph object is included in the selection. (#2844)

Added

  • Better magic underscore error messages. For example, some_fig.update_layout(geo_ltaxis_showgrid=True) shows Bad property path:\ngeo_ltaxis_showgrid\n ^ and lists the valid properties for geo.

Updated

  • Updated Plotly.js to version 1.57.1. See the plotly.js CHANGELOG for more information. These changes are reflected in the auto-generated plotly.graph_objects module.

[4.11.0] - 2020-10-01

Updated

  • Updated Plotly.js to version 1.56.0. See the plotly.js CHANGELOG for more information. These changes are reflected in the auto-generated plotly.graph_objects module.

[4.10.0] - 2020-09-10

Added

  • Added plotly.io.full_figure_for_development() and plotly.graph_objects.Figure.full_figure_for_development() (#2737)

Updated

  • The JSON serialization of plotly figures had been accelerated by handling differently figures with and without NaN and Inf values (#2880).

Updated

  • Updated Plotly.js to version 1.55.2. See the plotly.js CHANGELOG for more information. These changes are reflected in the auto-generated plotly.graph_objects module.
  • px.imshow has a new binary_string boolean argument, which passes the image data as a b64 binary string when True. Using binary strings allow for faster image rendering and smaller figure size. Additional optional arguments binary_backend, binary_format and binary_compression_level control how to generate the b64 string (#2691
  • px.imshow has a new contrast_rescaling argument in order to choose how to set data values corresponding to the bounds of the color range (#2691

Fixed

  • Plotly Express no longer converts datetime columns of input dataframes to UTC (#2749)
  • Plotly Express has more complete support for datetimes as additional hover_data (#2749)
  • Histogram selection behaviour with FigureWidget (#2711) with thanks to @meffmadd
  • Behaviour of full_html() with html=False (#2469) with thanks to @tallamjr
  • ff.distplot() now only computes traces that will be shown (#2730) with thanks to @akbo
  • Pandas backend .hist() works with latest version of Pandas (#2713) with thanks to @Kerybas

[4.9.0] - 2020-07-16

Added

  • Added image export support using Kaleido. The image export backend can be configured using the new engine argument to plotly.io.to_image and plotly.io.write_image. The engine argument may be set to "kaleido", "orca", or "auto". The default is engine="auto", in which case the Kaleido backend is enabled if the kaleido package from PyPI is installed, otherwise Orca is used. (#2613).
  • plotly.express.timeline() added as an official alternative to plotly.figure_factories.create_gantt() (#2626)
  • create_hexbin_mapbox() added to Figure Factories, with thanks to @RenaudLN for the impressive contribution!
  • facet_row_spacing and facet_col_spacing added to Plotly Express cartesian 2d functions (#2614)
  • base added to Plotly Express bar and bar_polar functions (#2626)
  • px.NO_COLOR constant to override wide-form color assignment in Plotly Express (#2614)

Fixed

  • trendline traces are now of type scattergl when render_mode="webgl" in Plotly Express (#2614)
  • regression from 4.8.1 whereby "parent" was not accepted as part of path for px.sunburst() and px.treemap() (#2640)
  • create_dendrogram() figure factory now works correctly with scipy 1.5.1 (#2627)

Updated

  • Updated Plotly.js to version 1.54.6. See the plotly.js CHANGELOG for more information.
  • Added all cartesian-2d Plotly Express functions, plus imshow, to Pandas backend with kind option (#2541)
  • plotly.express.imshow now uses data frame index and columns names and values to populate axis parameters by default (#2539)
  • Javascript extensions are now build using Node 12, and have an updated package-lock.json with many fewer security warnings (#2636)

[4.8.2] - 2020-06-26

Updated

  • Updated Plotly.js to version 1.54.5. See the plotly.js CHANGELOG for more information.
  • add_traces() now accepts bare int-like values for rows/cols as well as lists thereof (#2546), with thanks to @MCBoarder289 for the contribution!

Fixed

  • row/col now accept int-like values, not strictly int values (#2451), with thanks to @MCBoarder289 for the contribution!
  • Fixed special cases with px.sunburst and px.treemap with path input (#2524)
  • Fixed bug in hover_data argument of px functions, when the column name is changed with labels and hover_data is a dictionary setting up a specific format for the hover data (#2544).
  • Made the Plotly Express trendline argument more robust and made it work with datetime x values (#2554)
  • Fixed bug in px.sunburst and px.treemap: when the color and values arguments correspond to the same column, a different aggregation function has to be used for the two arguments (#2591)
  • Plotly Express wide mode now accepts mixed integer and float columns (#2598)
  • Plotly Express range_(x|y) should not impact the unlinked range of marginal subplots (#2600)
  • px.line now sets line_group=<variable> in wide mode by default (#2599)
  • Corrected some regex warnings (#2577), with thanks to @georgevdd for the contribution!

[4.8.1] - 2020-05-28

Fixed

  • Fixed the accidental removal of some functions and submodules from plotly.colors and plotly.express.colors

[4.8.0] - 2020-05-26

Added

  • plotly now provides a Plotly Express-backed Pandas-compatible plotting backend, which can be activated via pandas.options.plotting.backend = "plotly". Note that it is not intended to implement every Pandas plotting function, nor is it intended to replicate the behaviour of every argument, although per the changes below, x and y should behave similarly. (#2336)
  • New datasets have been added to plotly.express.data: stocks, experiment, medals_wide and medals_long. (#2336)
  • plotly go.Figure and go.FigureWidget now have a _repr_html_ and a _repr_mimebundle_ method, which are standard hooks for integration in systems based on IPython. In particular, with _repr_html_ plotly figures can now be used within sphinx-gallery without any scraper. These additions should not change anything to the way plotly figures are displayed in notebook environments, since the _ipython_display_ method (already present in earlier versions) takes precedence over the new methods.

Updated

  • The behaviour of the x, y, orientation, histfunc, violinmode, boxmode and stripmode arguments for 2d-cartesian functions in Plotly Express (i.e. scatter, line, area, bar, histogram, violin, box, strip, funnel, density_heatmap and density_contour) has been refined (#2336):
    • if x or y is missing, it is inferred to be the index of data_frame if data_frame provided, otherwise a stable index of integers starting at 0. In the case of px.bar, if the provided value is not continuous, the missing value is treated as a column of 1s named "count", so as to behave more like px.histogram and to avoid sizing the resulting bars differently based on their position in the column. Previously, missing values defaulted to integers starting at 0 per trace which made it potentially inconsistent or misleading.
    • if x (y) is missing, orientation now defaults to v (h). Previously it always defaulted to v but this is not considered a breaking change, as the cases in which it now defaults to h caused unreadable output if set to v.
    • if both x and y are provided and one of them does not contain continuous values, orientation defaults to the value perpendicular to that axis. Previously it always defaulted to v but this is not considered a breaking change, as the cases in which it now defaults to h caused unreadable output if set to v.
    • if either x or y (but not both) may now be provided as a list of column references into data_frame or columns of data, in which case the imputed data frame will be treated as "wide" data and melt()ed internally before applying the usual mapping rules, with function-specific defaults.
    • if neither x nor y is provided but data_frame is, the data frame will be treated as "wide" with defaults depending on the value of orientation (and orientation has accordingly been added to scatter, line, density_heatmap, and density_contour for this purpose). Previously this would have resulted in an empty figure.
    • if both x and y are provided to histogram, and if x, y and z are provided to density_heatmap or density_contour, then histfunc now defaults to sum so as to avoid ignoring the provided data, and to cause histogram and bar to behave more similarly.
    • violinmode, boxmode and stripmode now default to overlay if x (y) in in v (h) orientation is also mapped to color, to avoid strange spacing issues with the previous default of group in all cases.
  • The Plotly Express arguments color_discrete_map, symbol_map and line_dash_map now accept the string "identity" which causes the corresponding input data to be used as-is rather than mapped into color_discrete_sequence, symbol_sequence or line_dash_sequence, respectively. (#2336)
  • Plotly Express now accepts px.Constant or px.Range objects in the place of column references so as to express constant or increasing integer values. (#2336)

[4.7.1] - 2020-05-08

Fixed

  • Fix AttributeError: module 'plotly.graph_objs' has no attribute 'FigureWidget' exception on from plotly.graph_objs import * when ipywidgets is not installed. Error also occurred when importing plotly.figure_factor. It is now possible to import plotly.graph_objs.FigureWidget when ipywidgets is not installed, and an informative ImportError exception will be raised in the FigureWidget constructor (#2443, #1111).
  • Fix TypeError: unhashable type: 'Template' during Figure construction when plotly.io.templates.default is set to a Template object rather than a string.

[4.7.0] - 2020-05-06

Updated

  • Updated Plotly.js to version 1.54.1. See the plotly.js CHANGELOG for more information. The main new feature of this version of Plotly.js is the possibility to draw layout shapes, using custom dragmodes and corresponding modebar buttons.
  • The sphinx-gallery scraper has been updated to work with different structures of galleries #2149

Added

  • The hover_data parameter of px functions can now be a dictionary. This makes it possible to skip hover information for some arguments or to change the formatting of hover information #2377.
  • It's now possible to build a development version of Plotly.py against the build artifacts from a non-master branch of Plotly.js, which makes for faster QA and development cycles #2349. Thanks @zouhairm for this Pull Request!

Fixed

  • Plotly Express trendlines now handle missing data correctly #2357

Performance

This version includes several performance improvements (#2368, #2403).

  • Child graph objects (e.g. figure.layout.xaxis) are no longer created eagerly during graph object construction. Instead, they are created lazily the first time the property is accessed.
  • Property validation is now disabled for select internal operations.
  • When used with Python 3.7 and above, plotly.py now takes advantage of PEP-562 to perform submodule imports lazily. This dramatically improves import times.

[4.6.0] - 2020-03-31

Updated

  • Updated Plotly.js to version 1.53.0. See the plotly.js CHANGELOG for more information on the numerous new features and bug fixes of this release. The main features of the Plotly.js release are
    • Introduce range breaks on date axes (for example, to remove week-ends) via layout.xaxis.rangebreaks
    • Introduce a new unified x (or y) hovermode (layout.hovermode="x unified"), in which the hover box shows the information for all traces at a given x (or y) position
    • Add node.customdata and link.customdata to sankey traces
  • Updated contributing notes for more explanations on how to contribute to plotly.py #2290. Please give feedback on these notes!

[4.0.0] - 2019-07-16

This is a major release that includes many new features, and a few breaking changes. See the version 4 announcement for a summary of the important changes.

Updated

Added

  • The Plotly Express tech preview (https://medium.com/@plotlygraphs/introducing-plotly-express-808df010143d) has been integrated as the plotly.express module (#1613)
  • Added a new renderers framework the supports rendering figure in a wide variety of contexts (#1474). See the new Displaying Plotly Figures documentation page for more information.
  • Added plotly.io.write_html and plotly.io.to_html functions for exporting figures to HTML (1474). Also available as .write_html and .to_html figure methods.
  • Added new figure methods for batch updating figure properties (update_layout, update_traces, update_xaxes, etc.) (#1624). See the new Creating and Updating Figures documentation page for more details.
  • Added support for all trace types in make_subplots (#1528)
  • Added support for secondary y-axes in make_subplots (#1564)
  • Support passing a scalar trace object (rather than a list or tuple of trace objects) as the data property to the Figure constructor (#1614)
  • Added dictionary-style .pop method to graph object classes (#1614)
  • New jupyterlab-plotly JupyterLab extension for rendering figures in JupyterLab. Replaces the @jupyterlab/plotly-extension extension, and includes JupyterLab 1.0 support.
  • Added new suite of built-in colorscales to the plotly.colors module, and support for specifying this wide range of colorscales by name. Also added support for specifying colorscales as a list of colors, in which case the color spacing is assumed to be uniform (#1647).
  • Added sphinx-gallery renderer for embedding plotly figures in Sphinx-Gallery (#1577, plotly/plotly-sphinx-gallery).

Removed

  • The follow modules for interfacing with the Chart Studio cloud service have been removed from plotly.py and moved to the new chart-studio distribution package. The following modules have been moved to a new top-level chart_studio module:
    • plotly.plotly -> chart_studio.plotly
    • plotly.api -> chart_studio.api
    • plotly.dashboard_objs -> chart_studio.dashboard_objs
    • plotly.grid_objs -> chart_studio.grid_objs
    • plotly.presentation_objs -> chart_studio.presentation_objs
  • The legacy plotly.widgets.GraphWidget class for displaying online figures hosted by Chart Studio as ipywidgets has been removed. Please use the offline, and much more capable, plotly.graph_objects.FigureWidget class instead.
  • The fileopt argument to chart_studio.plotly.plot has been removed, so in-place modifications to previously published figures are no longer supported, and a figure will always overwrite a figure with the same name.

Changed

  • The 'plotly' template is used as the default theme across all figures.
  • In order to reduce the size of the core plotly distribution package, the bundled geographic shape files used by the create_choropleth figure factory have been moved to a new optional plotly-geo distribution package (1604)
  • For consistency with other figure factories, the create_choropleth and create_gantt figure factories now always returns Figure objects, rather than dictionaries (#1600, #1607).
  • Figure add trace methods (.add_trace, .add_traces, .add_scatter, etc.) now return a reference to the calling figure, rather than the newly created trace (#1624)
  • plotly.tools.make_subplots has been moved to plotly.subplots.make_subplots, though it is still available at the previous location for backward compatibility
  • The plotly.graph_objs module has been moved to plotly.graph_objects, though it is still available at the previous location for backward compatibility (#1614)
  • Trace uid properties are only generated automatically when a trace is added to a FigureWidget. When a trace is added to a standard Figure graph object the input uid, if provided, is accepted as is (#1580).
  • datetime objects that include timezones are not longer converted to UTC (#1581)
  • When a tuple property (e.g. layout.annotations) is updated with a list/tuple that is longer than the current value, the extra elements are appended to the end of the tuple.

Fixed

  • Fixed visibility of bar trace error bars in built-in templates (1656)

Updated

Fixed

Changed

  • Reverted change to layout.legend.itemsizing = 'constant' in built-in templates that was made in 3.8.0. This resulted in unexpectedly large legend entries in some common cases (#1526)

Updated

Added

Fixed

[3.5.0] - 2019-01-04

Updated

Changed

  • Plotly.js 1.43 converted title properties (e.g. layout.title) from strings into compound objects that contain the text as the text property along with new title placement attributes x, y, xref, yref, xanchor, yanchor and pad. Plotly.py 3.5.0 follows the new schema, but still supports specifying title as a string, in which case the string is assigned to the title.text property (#1302)
  • Plotly.js 1.43 also moved existing title* properties (e.g. layout.titlefont) under the title object (e.g. layout.title.font). Plotly.py 3.5.0 follows the new schema, but still supports the legacy title* properties by mapping them to the corresponding title.* property (#1302)
  • The update method on graph_objs now returns the updated object in order to support chaining multiple update operations together (#1379)
  • The show_link option has been set to False by default in the offline plot and iplot functions. Now that the "send data to cloud" button has been disabled by default in plotly.js 1.43.0, no buttons/links will be displayed by default that result in data being sent off of the local machine (#1304)
  • config options that are not known by plotly.py result in a warning but are still passed along to plotly.js. Prior to this change these unknown options were dropped silently (#1290)
  • Built-in themes now specify colorscales using the new global layout.colorscale properties. Previously the colorscales were defined for each trace type individually. This reduces the size of the resulting theme files (#1303)
  • Increased the maximum retry time of the orca integration from 8s to 30s (#1297)

Fixed

  • Fixed FigureWidget performance regression that, when working with large datasets, resulted in a slight freeze of the widget after user interactions (pan, zoom, etc) (1305)
  • Fix orca error when the ELECTRON_RUN_AS_NODE environment variable is set (#1293)
  • The 'responsive' config key was being silently blocked (#1290)
  • Fixed error when using unicode characters in string properties on Python 2 (#1289)
  • Removed invalid calls to non-existent validate and strip_style Figure methods in matplotlylib conversion logic (#1128)

[3.4.2] - 2018-11-23

Fixed

  • config options are now supported when using plotly.offline.iplot to display a figure in JupyterLab. Requires version 0.18.1 of the @jupyterlab/plotly-extension extension. (#1281, jupyterlab/jupyter-renderers#168)
  • Custom plotly_domain values are now supported in FigureWidget in both the classic notebook and JupyterLab (#1284)

[3.4.1] - 2018-11-09

Updated

Fixed

  • Fixed histogram binning with pandas Series or numpy array (regression introduced in 3.4.0) (#1257, plotly/plotly.js#3211)
  • Fixed incorrect validation error on the args property of layout.updatemenu.Button() when value is a list that starts with a list (#1265)
  • Fixed deadlock causing plotly.io.write_image to hang on Windows after exporting more than ~25 images (#1255)
  • Fixed plot display error for scattergl trace with mode='lines' and more than 100k points (#1271)
  • Fixed responsive resizing error with iplot in the classic notebook (#1263)

[3.4.0] - 2018-11-02

Updated

  • Updated Plotly.js to version 1.42.2. Select highlights included below, see the plotly.js CHANGELOG for more information.

Added

  • Default figure properties may now be customized using figure templates (themes) and 7 new predefined templates are bundled with plotly.py (#1224)
  • Added Parallel Categories (parcats) trace type for the visualization of multi-dimensional categorical datasets (plotly/plotly.js#2963)
  • Added LaTeX typesetting support for figures displayed in the Jupyter Notebook using plotly.offline.iplot and plotly.graph_objs.FigureWidget. Note: There are still outstanding issues with MathJax rendering in FireFox, but it is now working well in Chrome. (#1243)
  • Added include_mathjax argument to plotly.offline.plot to support the creation of HTML files with LaTeX typesetting (#1243)
  • Added new plotly.offline.get_plotlyjs function that returns the contents of the bundled plotly.js library as a string (#637, #1246)
  • Added new plotly.offline.get_plotlyjs_version function that returns the version of the bundled plotly.js library (#1246)
  • HTML div strings returned by plotly.offline.plot now contain logic to automatically resize the figure responsively. This logic was previously only added for html files. (#1043, #1234)
  • Figures displayed using plotly.offline.iplot in the classic Jupyter Notebook will now resize responsively (#1234)
  • Added 'cdn', 'directory', and path string include_plotlyjs options in plotly.offline.plot (#1234)
    • When 'cdn', the resulting html file/div includes a script tag reference to the plotlyjs cdn.
    • When 'directory', the resulting html file/div includes a script tag reference to a plotly.min.js bundle in the same directory as the html file. If output_type is 'file' then this plotly.min.js bundle is created in the output directory if it doesn't already exist.
    • When a string ending with '.js', the resulting html file/div includes a script tag that references this exact path. This can be used to point to a plotly.js bundle from an alternative CDN.
  • Added a new color_threshold argument to the create_dendrogram figure factory to control the dendrogram clustering cutoff (#995, #1075, #1214)
  • Added support for autorange='reversed' in 3D axes (#803, plotly/plotly.js#3141)
  • Added new gl3d tick and title auto-rotation algorithm that limits text overlaps (plotly/plotly.js#3084, plotly/plotly.js#3131)
  • Added modebar layout style attributes: orientation, bgcolor, color and activecolor (plotly/plotly.js#3068, plotly/plotly.js#3091)
  • Added title, titleposition and titlefont attributes to pie traces (plotly/plotly.js#2987)
  • Added hoverlabel.split attribute to ohlc and candlestick traces to split hover labels into multiple pieces (plotly/plotly.js#2959)
  • Added support for line.shape values 'hv', 'vh', 'hvh' and 'vhv' in scattergl traces (plotly/plotly.js#3087)
  • Added trace, node and link hoverinfo for sankey traces (#3096, #3150)
  • Added per-sector textfont settings in pie traces (#3130)

Changed

Fixed

  • Plotly's use of MathJax for LaTeX typesetting no longer interferes with the Jupyter Notebook's use of MathJax (#445, #360)
  • Fixed several issues with the use of reversescale=True in the create_annotated_heatmap figure factory (#1251)
  • Fixed case where plotly.offline.iplot would fail to render in the classic Jupyter Notebook if the notebook contained a Markdown headline with the text "Plotly" (#816)
  • None values in a scatter.hovertext list are now omitted from the hover label rather than being displayed as the string "None" (#1244)
  • Subplot titles created by plotly.tools.make_subplots are now positioned properly when custom row_width/column_width arguments are specified (#1229)
  • The bar.width property may now be specified as a numpy array or a pandas series (#1231, plotly/plotly.js#3169)
  • Error bars are now scaled correctly for logarithmic scatter3d traces (#1139)
  • Use uuid.uuid4 rather than uuid.uuid1 to work around an upstream Python bug (#1235, #1236)
  • The layout.grid.subplots property may now be specified as a 2D list of subplot identifiers (#1220, #1240)
  • Fixed scatter3d text alignment (#1055, plotly/plotly.js#3180)

    • @jupyterlab/plotly-extension@0.18

[3.3.0] - 2018-09-28

Updated

  • Updated Plotly.js to version 1.41.3. Select highlights included below, see the plotly.js CHANGELOG for more information.
  • Do not create or check permissions on the ~/.plotly configuration directory until a configuration write operation is performed (#1195). This change avoids some concurrency problems associated with running many instances of plotly.py simultaneously (#1068).

Added

  • Enable selection by clicking on points via new layout attribute clickmode and flag 'select' (#2944)
  • Added stacked area charts via new attributes stackgroup and stackgaps in scatter traces (#2960)
  • Added barpolar trace type - which replace and augment area traces (#2954)

Fixed

  • Replace use of pkg_resources.resource_string with pkgutil.get_data to improve compatibility with cx_Freeze (#1201)
  • An exception is no longer raised when an optional dependency raises an exception on import. The exception is logged and plotly.py continues as if the dependency were not installed (#1192)

    • jupyterlab==0.34

  • JupyterLab Extensions

    • plotlywidget@0.4.0
    • @jupyter-widgets/jupyterlab-manager@0.37
    • @jupyterlab/plotly-extension@0.17

[3.2.1] - 2018-09-14

This is a patch release that fixes a few bugs and reintroduces a few version 2 features that were not supported in version 3.

The bundled version of plotly.js remains at 1.40.1

JupyterLab Versions

For use with JupyterLab, the following versions of the following packages must be installed:

  • Python Packages

    • plotly==3.2.1
    • ipywidgets>=7.2
    • notebook>=5.3
    • jupyterlab==0.34

  • JupyterLab Extensions

    • plotlywidget@0.3.0
    • @jupyter-widgets/jupyterlab-manager@0.37
    • @jupyterlab/plotly-extension@0.17

Added

  • An optional skip_invalid argument has been added to the Figure and FigureWidget constructors. By default, skip_invalid is False and invalid figure properties will result in an exception (this is identical to the previous behavior). When skip_invalid is set to True, invalid properties will instead be silently ignored. This argument replaces the _raise argument that was available in version 2, and makes it possible to import figure definitions from different plotly versions, where incompatible properties are ignored rather than causing an exception.
  • A to_ordered_dict method has been added to the Figure and FigureWidget classes. This method returns a representation of the figure as a nested structure of OrderedDict and list instances where the keys in each OrderedDict are sorted alphabetically. This method replaces the get_ordered method that was available in version 2, and makes it possible to traverse the nested structure of a figure in a deterministic order.

Fixed

[3.0.0] - 2018-07-05

This is a major version with many exciting updates. See the Introducing plotly.py 3.0.0 post for more information.

JupyterLab plotlywidget version: 0.1.1

Plotly.js version: 1.38.3

Added

  • Full Jupyter ipywidgets integration with the new graph_objs.FigureWidget class
  • FigureWidget figures can be updated interactively using property assignment syntax
  • The full trace and layout API is generated from the plotly schema to provide a great experience for interactive use in the notebook

  • Context manager API for animation. Run help(go.Figure().batch_animate) for the full doc string.
  • Perform automatic retries when communicating with plot.ly services. This introduces a new required dependency on the retrying library.
  • Improved data validation covering the full API with clear, informative error messages. This means that incorrect properties and/or values now always raise a ValueError with a description of the error, the invalid property, and the available properties on the level that it was placed in the graph object. Eg. go.Scatter(foo=123) raises a validation error. See https://plot.ly/python/reference/ for a reference to all valid properties and values in the Python API.
  • Error message for plotly.figure_factory.create_choropleth is now helpful to Anaconda users who do not have the correct modules installed for the County Choropleth figure factory.

  • Offline plots created with plotly.offline.plot now resize as expected when the window is resized.
  • plotly.figure_factory.create_distplot now can support more than 10 traces without raising an error. Updated so that if the list of colors (default colors too) is less than your number of traces, the color for your traces will loop around to start when it hits the end.

[2.0.1] - 2017-02-07

Added

  • Support for rendering plots in nteract! See nteract/nteract#662 for the associated PR in nteract.
  • As part of the above, plotly output now prints with a custom mimetype - application/vnd.plotly.v1+json
  • memoize decorator added to plotly.utils

Changed

  • a Grid from plotly.grid_objs now accepts a pandas.Dataframe as its argument.
  • computationally-intensive graph_reference functions are memoized.

[2.0.0] - 2017-01-25

Changed

  • plotly.exceptions.PlotlyRequestException is always raised for network failures. Previously either a PlotlyError, PlotlyRequestException, or a requests.exceptions.ReqestException could be raised. In particular, scripts which depend on try-except blocks containing network requests should be revisited.
  • plotly.py:sign_in now validates to the plotly server specified in your config. If it cannot make a successful request, it raises a PlotlyError.
  • plotly.figure_factory will raise an ImportError if numpy is not installed.
  • plotly.figure_factory.create_violin() now has a rugplot parameter which determines whether or not a rugplot is draw beside each violin plot.

Deprecated

  • plotly.tools.FigureFactory. Use plotly.figure_factory.*.
  • (optional imports) plotly.tools._*_imported It was private anyhow, but now it's gone. (e.g., _numpy_imported)
  • (plotly v2 helper) plotly.py._api_v2 It was private anyhow, but now it's gone.

[1.13.0] - 2016-12-17

Added

  • Python 3.5 has been added as a tested environment for this package.

Updated

  • plotly.plotly.create_animations and plotly.plotly.icreate_animations now return appropriate error messages if the response is not successful.
  • frames are now integrated into GRAPH_REFERENCE and figure validation.

Changed

  • The plot-schema from https://api.plot.ly/plot-schema is no longer updated on import.

[1.12.12] - 2016-12-06

Updated

  • Updated plotly.min.js to version 1.20.5 for plotly.offline.
  • FF.create_scatterplotmatrix now by default does not show the trace labels for the box plots, only if diag=box is selected for the diagonal subplot type.

[1.12.11] - 2016-12-01

Fixed

  • The link text in the bottom right corner of the offline plots now properly displays Export to [Domain Name] for the given domain name set in the users' .config file.

[1.12.10] - 2016-11-28

Updated

  • FF.create_violin and FF.create_scatterplotmatrix now by default do not print subplot grid information in output
  • Removed alert that occurred when downloading plot images offline. Please note: for higher resolution images and more export options, consider making requests to our image servers. See: help(py.image) for more details.

Added

  • Plot configuration options for offline plots. See the list of configuration options and examples for more information.
    • Please note that these configuration options are for offline plots ONLY. For configuration options when embedding online plots please see our embed tutorial.
  • colors.py file which contains functions for manipulating and validating colors and arrays of colors
  • 'scale' param in FF.create_trisurf which now can set the interpolation on the colorscales
  • animations now work in offline mode. By running plotly.offline.plot() and plotly.offline.iplot() with a fig with frames, the resulting plot will cycle through the figures defined in frames either in the browser or in an ipython notebook respectively. Here's an example:
import IPython.display
from IPython.display import display, HTML
from plotly.offline import download_plotlyjs, init_notebook_mode, plot, iplot
init_notebook_mode(connected=True)

figure_or_data = {'data': [{'x': [1, 2], 'y': [0, 1]}],
                  'layout': {'xaxis': {'range': [0, 3], 'autorange': False},
                             'yaxis': {'range': [0, 20], 'autorange': False},
                  'title': 'First Title'},
                  'frames': [{'data': [{'x': [1, 2], 'y': [5, 7]}]},
                             {'data': [{'x': [-1, 3], 'y': [3, 9]}]},
                             {'data': [{'x': [2, 2.6], 'y': [7, 5]}]},
                             {'data': [{'x': [1.5, 3], 'y': [7.5, 4]}]},
                             {'data': [{'x': [1, 2], 'y': [0, 1]}],
                              'layout': {'title': 'End Title'}}]}
iplot(figure_or_data)

More examples can be found at https://plot.ly/python/animations/.

  • animations now work in online mode: use plotly.plotly.create_animations and plotly.plotly.icreate_animations which animate a figure with the frames argument. Here is a simple example:
import plotly.plotly as py
from plotly.grid_objs import Grid, Column

column_1 = Column([0.5], 'x')
column_2 = Column([0.5], 'y')
column_3 = Column([1.5], 'x2')
column_4 = Column([1.5], 'y2')

grid = Grid([column_1, column_2, column_3, column_4])
py.grid_ops.upload(grid, 'ping_pong_grid', auto_open=False)

# create figure
figure = {
    'data': [
        {
            'xsrc': grid.get_column_reference('x'),
            'ysrc': grid.get_column_reference('y'),
            'mode': 'markers',
        }
    ],
    'layout': {'title': 'Ping Pong Animation',
               'xaxis': {'range': [0, 2], 'autorange': False},
               'yaxis': {'range': [0, 2], 'autorange': False},
               'updatemenus': [{
                   'buttons': [
                       {'args': [None],
                        'label': u'Play',
                        'method': u'animate'}
               ],
               'pad': {'r': 10, 't': 87},
               'showactive': False,
               'type': 'buttons'
                }]},
    'frames': [
        {
            'data': [
                {
                    'xsrc': grid.get_column_reference('x2'),
                    'ysrc': grid.get_column_reference('y2'),
                    'mode': 'markers',
                }
            ]
        },
        {
            'data': [
                {
                    'xsrc': grid.get_column_reference('x'),
                    'ysrc': grid.get_column_reference('y'),
                    'mode': 'markers',
                }
            ]
        }
    ]
}

py.create_animations(figure, 'ping_pong')

Fixed

  • Trisurf now uses correct Plotly Colorscales when called
  • Fixed a bug in the format of unique-identifiers in columns of grids that are uploaded to plotly via plotly.plotly.upload. See #599 for details. In particular, creating plots that are based off of plotly grids is no longer broken. Here is an example:
import plotly.plotly as py
from plotly.grid_objs import Grid, Column

c1 = Column([6, 6, 6, 5], 'column 1')
c2 = Column(['a', 'b', 'c', 'd'], 'column 2')
g = Grid([c1, c2])

# Upload the grid
py.grid_ops.upload(g, 'my-grid', auto_open=False)

# Make a graph that with data that is referenced from that grid
trace = Scatter(xsrc=g[0], ysrc=g[1])
url = py.plot([trace], filename='my-plot')

Then, whenever you update the data in 'my-grid', the associated plot will update too. See https://plot.ly/python/data-api for more details on usage and examples.

[1.12.9] - 2016-08-22

Fixed

  • the colorbar in .create_trisurf now displays properly in offline mode.

Updated

  • the colorbar in .create_trisurf now displays the appropriate max and min values on the ends of the bar which corresponding to the coloring metric of the figure
  • edges_color is now a param in .create_trisurf which only takes rgb values at the moment

[1.12.8] - 2016-08-18

Fixed

  • Fixed color bug with trisurf plots where certain triangles were colored strangely. The coordinates of rgb(...) are now rounded to their nearest integer (using Python3 method of rounding), then placed in the color string to fix the issue.

[1.12.7] - 2016-08-17

Fixed

  • Edited plotly.min.js due to issue using iplot to plot offline in Jupyter Notebooks
    • Please note that plotly.min.js may be cached in your Jupyter Notebook. Therefore, if you continue to experience this issue after upgrading the Plotly package please open a new notebook or clear the cache to ensure the correct plotly.min.js is referenced.

[1.12.6] - 2016-08-09

Updated

  • Updated plotly.min.js from 1.14.1 to 1.16.2
    • Trace type scattermapbox is now part of the main bundle

  • Updated default-schema

Added

  • Added update_plotlyjs_for_offline in makefile in order to automate updating plotly.min.js for offline mode

[1.12.2] - 2016-06-20

Updated

  • Updated plotly.min.js so the offline mode is using plotly.js v1.13.0
    • Fix Plotly.toImage and Plotly.downloadImage bug specific to Chrome 51 on OSX
    • Beta version of the scattermapbox trace type - which allows users to create mapbox-gl maps using the plotly.js API. Note that scattermapbox is only available through custom bundling in this release.
    • See the plotly.js CHANGELOG for additional additions and updates.

Added

  • The FigureFactory can now create gantt charts with .create_gantt. Check it out with:
import plotly.tools as tls
help(tls.FigureFactory.create_gantt)
  • Ability to download images in offline mode. By providing an extra keyword image to the existing plot calls, you can now download the images of the plots you make in offline mode.

Fixed

  • Fixed check for the height parameter passed to _plot_html, and now sets the correct link text for plots generated in offline mode.

[1.12.1] - 2016-06-19

Added

  • The FigureFactory can now create violin plots with .create_violin. Check it out with:
import plotly.tools as tls
help(tls.FigureFactory.create_violin)

[1.12.0] - 2016-06-06

Added

  • Added ability to enable/disable SSL certificate verification for streaming. Disabling SSL certification verification requires Python v2.7.9 / v3.4.3 (or above). This feature can be toggled via the plotly_ssl_verification configuration setting.

[1.11.0] - 2016-05-27

Updated

  • Changed the default option for create_distplot in the figure factory from probability to probability density and also added the histnorm parameter to allow the user to choose between the two options. Note: This is a backwards incompatible change.

  • Updated plotly.min.js so the offline mode is using plotly.js v1.12.0

    • Light position is now configurable in surface traces
    • surface and mesh3d lighting attributes are now accompanied with comprehensive descriptions

  • Allowed create_scatterplotmatrix and create_trisurf to use divergent and categorical colormaps. The parameter palette has been replaced by colormap and use_palette has been removed. In create_scatterplotmatrix, users can now:

    • Input a list of different color types (hex, tuple, rgb) to colormap to map colors divergently
    • Use the same list to categorically group the items in the index column
    • Pass a singlton color type to colormap to color all the data with one color
    • Input a dictionary to colormap to map index values to a specific color
    • 'cat' and 'seq' are valid options for colormap_type, which specify the type of colormap being used

  • In create_trisurf, the parameter dist_func has been replaced by color_func. Users can now:

    • Input a list of different color types (hex, tuple, rgb) to colormap to map colors divergently
    • Input a list|array of hex and rgb colors to color_func to assign each simplex to a color

Added

  • Added the option to load plotly.js from a CDN by setting the parameter connected=True in the init_notebook_mode() function call
  • The FigureFactory can now create trisurf plots with .create_trisurf. Check it out with:
import plotly.tools as tls
help(tls.FigureFactory.create_trisurf)

[1.10.0] - 2016-05-19

Fixed

  • Version 1.9.13 fixed an issue in offline mode where if you ran init_notebook_mode more than once the function would skip importing (because it saw that it had already imported the library) but then accidentally clear plotly.js from the DOM. This meant that if you ran init_notebook_mode more than once, your graphs would not appear when you refreshed the page. Version 1.9.13 solved this issue by injecting plotly.js with every iplot call. While this works, it also injects the library excessively, causing notebooks to have multiple versions of plotly.js inline in the DOM, potentially making notebooks with many iplot calls very large. Version 1.10.0 brings back the requirement to call init_notebook_mode before making an iplot call. It makes init_notebook_mode idempotent: you can call it multiple times without worrying about losing your plots on refresh.

[1.9.13] - 2016-05-19

Fixed

  • Fixed issue in offline mode related to the inability to reload plotly.js on page refresh and extra init_notebook_mode calls.

[1.9.12] - 2016-05-16

Added

  • SSL support for streaming.

[1.9.11] - 2016-05-02

Added

  • The FigureFactory can now create scatter plot matrices with .create_scatterplotmatrix. Check it out with:
import plotly.tools as tls
help(tls.FigureFactory.create_scatterplotmatrix)

[1.9.10] - 2016-04-27

Updated

  • Updated plotly.min.js so the offline mode is using plotly.js v1.10.0
    • Added beta versions of two new 2D WebGL trace types: heatmapgl, contourgl
    • Added fills for scatterternary traces
    • Added configurable shapes layer positioning with the shape attribute: layer

[1.9.9] - 2016-04-15

Fixed

  • Fixed require is not defined issue when plotting offline outside of Ipython Notebooks.

[1.9.8] - 2016-04-14

Fixed

  • Error no longer results from a "Run All" cells when working in a Jupyter Notebook.

Updated

  • Updated plotly.min.js so offline is using plotly.js v1.9.0
    • Added Ternary plots with support for scatter traces (trace type scatterternary, currently only available in offline mode)
    • For comprehensive update list see the plotly.js CHANGELOG

[1.9.7] - 2016-04-04

Fixed

  • Offline mode will no longer delete the Jupyter Notebook's require, requirejs, and define variables.

Updated

  • Updated plotly.min.js so offline is using plotly.js v1.8.0
    • Added range selector functionality for cartesian plots
    • Added range slider functionality for scatter traces
    • Added custom surface color functionality
    • Added ability to subplot multiple graph types (SVG cartesian, 3D, maps, pie charts)
    • For comprehensive update list see the plotly.js CHANGELOG

[1.9.6] - 2016-02-18

Updated

  • Updated plotly.min.js so offline is using plotly.js v1.5.2

[1.9.5] - 2016-01-17

Added

  • Offline matplotlib to Plotly figure conversion. Use offline.plot_mpl to convert and plot a matplotlib figure as a Plotly figure independently of IPython/Jupyter notebooks or use offline.iplot_mpl to convert and plot inside of IPython/Jupyter notebooks. Additionally, use offline.enable_mpl_offline to convert and plot all matplotlib figures as plotly figures inside an IPython/Jupyter notebook. See examples below:

An example independent of IPython/Jupyter notebooks:

from plotly.offline import init_notebook_mode, plot_mpl
import matplotlib.pyplot as plt

init_notebook_mode()

fig = plt.figure()
x = [10, 15, 20]
y = [100, 150, 200]
plt.plot(x, y, "o")

plot_mpl(fig)

An example inside of an IPython/Jupyter notebook:

from plotly.offline import init_notebook_mode, iplot_mpl
import matplotlib.pyplot as plt

init_notebook_mode()

fig = plt.figure()
x = [10, 15, 20]
y = [100, 150, 200]
plt.plot(x, y, "o")

iplot_mpl(fig)

An example of enabling all matplotlib figures to be converted to Plotly figures inside of an IPython/Jupyter notebook:

from plotly.offline import init_notebook_mode, enable_mpl_offline
import matplotlib.pyplot as plt

init_notebook_mode()
enable_mpl_offline()

fig = plt.figure()
x = [10, 15, 20, 25, 30]
y = [100, 250, 200, 150, 300]
plt.plot(x, y, "o")
fig

[1.9.4] - 2016-01-11

Added

  • Offline plotting now works outside of the IPython/Jupyter notebook. Here's an example:
from plotly.offline import plot
from plotly.graph_objs import Scatter

plot([Scatter(x=[1, 2, 3], y=[3, 1, 6])])

This command works entirely locally. It writes to a local HTML file with the necessary plotly.js code to render the graph. Your browser will open the file after you make the call.

The call signature is very similar to plotly.offline.iplot and plotly.plotly.plot and plotly.plotly.iplot, so you can basically use these commands interchangeably.

If you want to publish your graphs to the web, use plotly.plotly.plot, as in:

import plotly.plotly as py
from plotly.graph_objs import Scatter

py.plot([Scatter(x=[1, 2, 3], y=[5, 1, 6])])

This will upload the graph to your online plotly account.

[1.9.3] - 2015-12-08

Added

  • Check for no_proxy when determining if the streaming request should pass through a proxy in the chunked_requests submodule. Example: no_proxy='my_stream_url' and http_proxy=my.proxy.ip:1234, then my_stream_url will not get proxied. Previously it would.

[1.9.2] - 2015-11-30

Bug Fix: Previously, the "Export to plot.ly" link on offline charts would export your figures to the public plotly cloud, even if your config_file (set with plotly.tools.set_config_file to the file ~/.plotly/.config) set plotly_domain to a plotly enterprise URL like https://plotly.acme.com.

This is now fixed. Your graphs will be exported to your plotly_domain if it is set.

[1.9.1] - 2015-11-26

Added

  • The FigureFactory can now create annotated heatmaps with .create_annotated_heatmap. Check it out with:
import plotly.tools as tls
help(tls.FigureFactory.create_annotated_heatmap)
  • The FigureFactory can now create tables with .create_table.
import plotly.tools as tls
help(tls.FigureFactory.create_table)

[1.9.0] - 2015-11-15

  • Previously, using plotly offline required a paid license. No more: plotly.js is now shipped inside this package to allow unlimited free use of plotly inside the ipython notebook environment. The plotly.js library that is included in this package is free, open source, and maintained independently on GitHub at https://github.com/plotly/plotly.js.
  • The plotly.js bundle that is required for offline use is no longer downloaded and installed independently from this package: plotly.offline.download_plotlyjs is deprecated.
  • New versions of plotly.js will be tested and incorporated into this package as new versioned pip releases; plotly.js is not automatically kept in sync with this package.

[1.8.12] - 2015-11-02

  • Big data warning mentions plotly.graph_objs.Scattergl as possible solution.

[1.8.9] - 2015-10-11

[1.8.8] - 2015-10-05

  • Sometimes creating a graph with a private share-key doesn't work - the graph is private, but not accessible with the share key. Now we check to see if it didn't work, and re-try a few times until it does.

[1.8.7] - 2015-10-01

Added

  • The FigureFactory can now create dendrogram plots with .create_dendrogram.

[1.8.6] - 2015-09-28

Fixed

  • Saving "world_readable" to your config file via plotly.tools.set_config actually works.

Added

  • You can also save auto_open and sharing to the config file so that you can forget these keyword argument in py.iplot and py.plot.

[1.8.5] - 2015-09-29

Fixed

  • Fixed validation errors (validate=False workaround no longer required)

Added

  • Auto-sync API request on import to get the latest schema from Plotly
  • .-access for nested attributes in plotly graph objects
  • General .help() method for plotly graph objects
  • Specific attribute .help(<attribute>) also included

Removed

  • No more is streamable, streaming validation.

[1.8.3] - 2015-08-14

Fixed

  • Fixed typos in plot and iplot documentations

[1.8.2] - 2015-08-11

Added

  • CHANGELOG
  • sharing keyword argument for plotly.plotly.plot and plotly.plotly.iplot with options 'public' | 'private' | 'secret' to control the privacy of the charts. Depreciates world_readable

Changed

  • If the response from plot or iplot contains an error message, raise an exception

Removed

  • height and width are no longer accepted in iplot. Just stick them into your figure's layout instead, it'll be more consistent when you view it outside of the IPython notebook environment. So, instead of this:

    py.iplot([{'x': [1, 2, 3], 'y': [3, 1, 5]}], height=800)

    do this:

    py.iplot({
  'data': [{'x': [1, 2, 3], 'y': [3, 1, 5]}],
  'layout': {'height': 800}
})

Fixed

  • The height of the graph in iplot respects the figure's height in layout
