This plugin allows you to easily create HTML canvas based graphs on your WordPress blog. It uses the simple HTML5 Graph script by Chris Valleskey with modifications by me to adjust the labels and allow the first data point to show properly.
[graph argument="value" ...]CSV Data[/graph]
[graph id="example" background="#f9f8f7" width="446" height="200" grid="20,10" leftOffset="14" showshadow="true"]0,10,20,30,40,50,60,70[/graph]
id: Defines the id of the canvas element, such as "graph".
showline: Boolean value. Will show or hide the line on the graph.
lineWidth: Decimal value. The width of the line if it is being show and greater than 0.
strokeStyle: Hexadecimal color or rgba() value. This is the color and opacity of the line.
showfill: Boolean value. Will show or hide the fill beneath the lines on the graph.
fillStyle: Hexadecimal color or rgba() value. This is the color and opacity of the fill beneath the lines.
showdots: Boolean value. Will show or hide the actual dots on the lines on the graph.
showgrid: Boolean value. Will show or hide the grid.
grid: [Decimal, Decimal] value. This sets the grids width and heigh for each unit.
gridcolor: Hexadecimal color or rgba() value. This is the color and opacity of the grid lines.
background: Hexadecimal color or rgba() value. This is the color and opacity of the background of the canvas.
showlabels: Boolean value. Will show or hide the labels on the grid.
labelfilter: String value. This is a string where %label% will be replaced with the actual label value, so something like $%label% might become $40.
range: [Decimal, Decimal] value. This sets maximum and minimum range for data on the grids Y axis.
leftOffset: Decimal value. This defines the starting offset from the left and is used to allow longer labels to show the first point clearly.
call: This is a callback function that will return a single value when called for a live graph, such as randomNumbers where the function looks like function randomNumbers(){return Math.floor(Math.random()*100) + 50;}.
interval: Integer value. This sets the interval between calls when using the call parameter.
