Hi:
I tried your change, and it works well. I used:
p.xaxis.major_label_overrides = dict(zip(range(len(xticks)), xticks))
p.xaxis.major_label_orientation = 'vertical'
p.xaxis.ticker = list(range(len(xticks)))
Yes, this is categorical data. However, we like to use line plots so we can superimpose the results on the same chart. Bar charts don't lend themselves as well to have many independent trials. You can think of the plots as connecting the tops of the bars to produce a behavioral curve.
Thanks,

Hi,
You question is a bit underspecified, it sounds like you have a continuous numeric axis (not a categorical axis), but that you want to label fixed positions in a custom way?
Then you can set .ticker on the axis to specify fixed tick positions:
bokeh.models.axes — Bokeh 0.12.10 documentation
And you can set .major_label_overrides on the axis to map those fixed positions to arbitrary labels:
bokeh.models.axes — Bokeh 0.12.10 documentation
Something like:
p.xaxis.ticker = [ 1, 5, 10 ]
p.xaxis.major_label_overrides = { 1: 'a', 5: 'b', 10: 'c' }
If you have actual categorical data and axes, you should refer to this chapter of the users guide:
Handling Categorical Data — Bokeh 0.12.10 documentation
Thanks,
Bryan

Unfortunately, the example on the web shows you referring to a 'tick' parameter and there's no apparent way to pass in data to this function, so I don't have an easy way to accomplish this.
