[Matplotlib-users] X-ticklabels not working in histogram?

[Victor H. <vic...@ya...>]

heya,

I'm trying to use Matplotlib to generate a histogram of some measurements:

import matplotlib
matplotlib.use('Agg')
import matplotlib.pyplot as pyplot
...
fig = pyplot.figure()
ax = fig.add_subplot(1,1,1,)
n, bins, patches = ax.hist(measurements, bins=50, range=(graph_minimum,
graph_maximum), histtype='bar')
ax.set_xticklabels([n], rotation='vertical')

for patch in patches:
    patch.set_facecolor('r')
pyplot.title='Foobar'
#pyplot.grid(True)
pyplot.xlabel('X-Axis')
pyplot.ylabel('Y-Axis')
pyplot.savefig(output_filename)

However, the x-tick-labels doesn't seem to be working:

Instead of appearing on the bottom underneath each bar, it's rendered as a
single line of numbers at the bottom left - which is also truncated.

Also, the plot title doesn't seem to appear in my ouputed PNG.

Any ideas as to what's going on?

Cheers,
Victor
