Setting the tick label font size

Community matplotlib-users

Hello,

I'm trying to change the font size for the tick labels. I've tried both
setting it explicitly when creating the labels:

  ax2.set_xticklabel(['%d' % x for x in arange(10)], fontsize=10)

or after:

  for label in ax2.get_xticklabels():
      label.set_fontsize(8)

but the rendering is unaffected by the setting. This is with the MacOSX
backend and with the PDF backend. Is it a bug or am I missing something?

Thanks. Best,
Daniele

Hi Daniele,

not sure, but it seems to work for me. Did you do a plt.draw() or plt.show() to reflect the changes?

Kind regards,

Oliver

Hello,

it investigated this a bit further and the problem presents itself only
when I use `mpl_toolkits.axisartist.Axes`. Here is a minimum example
that demonstrates the problem:

import numpy as np
import matplotlib.pyplot as plt

from mpl_toolkits.axes_grid1 import host_subplot
from mpl_toolkits.axisartist import Axes

x = np.linspace(0, 2*np.pi)
y = np.sin(x)

f = plt.figure()

BUG = True
if BUG:
    ax1 = host_subplot(111, axes_class=Axes)
else:
    ax1 = host_subplot(111, axes_class=Axes)

ax1.plot(x, y)
ax1.set_xlim(0, 2*np.pi)
ax1.set_xticks(np.linspace(0, 2*np.pi, 5))
ax1.set_xticklabels(['%.2f' % x for x in np.linspace(0, 2*np.pi, 5)],
fontsize=8)

plt.draw()
plt.show()

Cheers,
Daniele
