I am trying to rotate the major- and the minor axis within a multi-categorical plot in Bokeh (similar to what is done for major tick labels here and done within matplotlib here. When having several categories, their labels/text often get smeared together.
Taking some inspiration from the Bokeh documentation on Categorical Data the result, using Bokehs vbar functionality, would look something like
The major axis can be set using
p.xaxis.major_label_orientation = pi/4
Yet I can't find any way of actually doing the same for the minors...
? p.xaxis.minor[0]_label_orientation = pi/4 ?
? p.xaxis.minor[1]_label_orientation = pi/3 ?
...
Any thoughts out there would be very much appreciated!
UPDATE
This capability was added in Bokeh 0.12.16, you can now do:
p.xaxis.major_label_orientation = "vertical"
p.xaxis.subgroup_label_orientation = "normal"
p.xaxis.group_label_orientation = 0.8
It's not possible in Bokeh 0.12.13, the orientation of labels for levels other than the first one is always parallel: https://github.com/bokeh/bokeh/blob/0.12.13/bokehjs/src/coffee/models/axes/categorical_axis.coffee#L89-L92
You're welcome to create a GitHub issue with a feature request if you need this functionality.
