button to change axis scale

[man74cio]

Hello,
I'm trying to replace a figure written in d3js with one written in bokeh.
My old figure had the ability to change the scale of an axis (log/linear) with a button, but I can't achieve the same thing with bokeh. I tried using y_axis_type, but although it works when creating the figure as a variable, it's not an attribute of the figure and therefore cannot be used.
How can I accomplish this ?
