Rotating X-Labels on AxesGrid?

Community matplotlib-users

Hey folks,

I'm trying to make some bar plots using AxesGrid and the set_xlabels method doesn't seem to notice that I'm passing a 'rotation' kwarg.

Here's a small script that showing that this doesn't work:
# ------------------------------------------
import matplotlib.pyplot as pl
from mpl_toolkits.axes_grid import AxesGrid

fig = pl.figure()
grid = AxesGrid(fig, 111, nrows_ncols=(1,1), axes_pad=0.12)
xlabs = ['paul', 'chris', 'patti']

for ax in grid:
    ax.plot([1,2,3], [2,2.5,3], 'bo')
    ax.set_ylim([0,5])
    ax.set_xlim([0,4])
    ax.set_xticks([1,2,3])
    ax.set_xticklabels(xlabs, rotation=90)
# -----------------------------------------

As you can see from the attached image, my labels aren't rotating. This is obviously a trivial example, but I'm trying to plot some chemical concentrations and the names are quite long.

Any tips? Should I just be using subpolot instead?

Python 2.6.2 and:
In [25]: import matplotlib as mpl
In [26]: mpl.__version__
Out[26]: '0.99.1'
In [27]: import numpy as np
In [28]: np.__version__
Out[28]: '1.3.0'

Thanks!

First of all, unless you're displaying multiple images (with aspect),
there is not much of benefit of using axes_grid toolkit. So I
strongly recommend you to stick to subplot.

axes_grid toolkit uses different kind of artists to draw ticklabels.
Therefore, most of the matplotlib command that try to change the
properties of the ticklabels does not work.

You may recover the original matplotlib behavior, but some of the
feature in axes_grid toolkit won't work.

http://matplotlib.sourceforge.net/mpl_toolkits/axes_grid/users/overview.html#axisline

axes_grid way of rotating ticklabels is

   ax.axis["bottom"].major_ticklabels.set_rotation(90)

But, you may want to fiddle with other properties also.

   ax.axis["bottom"].major_ticklabels.set_va("top")
   ax.axis["bottom"].major_tick_pad = -8

Anyhow, I must admit that handling of ticklabels in axes_grid toolkit
is a bit messy currently. And I hope to improve it soon.
