Re: [Matplotlib-users] tick labels in colorbar?
Hi,
thanks for the suggestion.
ax.set_xticks((-pi,pi))
ax.set_xticklabels(('$-\pi$','$\pi$'))
I guess color bars are a little special in the sense that
AttributeError: Colorbar instance has no attribute 'set_yticklabels'
The tick positions are given not by set_yticks either, but as an option
pylab.colorbar(ticks=(-pi,0,pi))
at the instatiation of the bar. It would indeed be very handy if the
bars acted like axes.
Cheers,
Nico

Hi Nico,
nontheless you can use the axes-method to display your preferred labels. The
colorbar has its axes as attribute 'ax' (see also my small example below):
cb.ax.set_yticklabels((r'$-\pi$', '0', r'$\pi$'))
Kind regards,
Matthias

import matplotlib as mpl
mpl.rc('text', usetex=True)
import matplotlib.pyplot as plt
import numpy as np
ax = plt.axes()
plt.imshow(np.reshape(np.pi*np.arange(-2, 3, 0.5), (2, 5)))
cb = plt.colorbar()
cb.set_ticks((-np.pi, 0.0, np.pi))
cb.ax.set_yticklabels((r'$-\pi$', '0', r'$\pi$'))
plt.show()

cb.ax.set_yticklabels((r'$-\pi$', '0', r'$\pi$')) Works like a charm.

[Matplotlib-users] tick labels in colorbar?
Hi, I'm plotting a colorbar with pylab.colorbar(ticks=(-pi,0,pi)) and trying to add proper \pi labels to it. Couldn't find out how to do that from the manual -- any hints here?

Re: [Matplotlib-users] tick labels in colorbar?
Hi Nico,
I didn't test it, but maybe with something like that:
rc('text', usetex=True)
[taken from
http://matplotlib.sourceforge.net/plot_directive/mpl_examples/pylab_examples/tex_demo.py]
ax.set_xticks((-pi,pi))
ax.set_xticklabels(('$-\pi$','$\pi$'))

Cheers,
Philipp
