ticklabels font using latex #11586
Description
I can not change the fontstyle of the ticklabels to "sans-serif" when using latex.
import matplotlib.pyplot as plt
import numpy as np
from matplotlib import rc
rc('font',**{'family':'sans-serif','sans-serif':['Helvetica']})
rc('text', usetex=True)
def xticklabels_example():
fig = plt.figure()
x = np.arange(20)
y1 = np.cos(x)
y2 = (x**2)
y3 = (x**3)
yn = (y1,y2,y3)
COLORS = ('b','g','k')
for i,y in enumerate(yn):
ax = fig.add_subplot(len(yn),1,i+1)
ax.plot(x, y, ls='solid', color=COLORS[i])
if i != len(yn) - 1:
# all but last
ax.set_xticklabels( () )
else:
for tick in ax.xaxis.get_major_ticks():
tick.label.set_fontsize(14)
# specify integer or one of preset strings, e.g.
#tick.label.set_fontsize('x-small')
tick.label.set_rotation('vertical')
fig.suptitle('Matplotlib xticklabels Example')
plt.show()

That makes sense to me. OTOH, we maybe could do a better job of documenting this. I don't think its trivial for a user to know that they need to setup TeX by hand this way.
Possibly more info at?

I am trying to come up with a good documentation entry for this. Found 3 other issues that have the same root cause (i.e. not knowing that changing text font in TeX doesn't automatically change the math font) -- #8436, #6041, #3999.

I think an entry that says “font selection using tex” or some such would be helpful. Show changing the basic font and the math font.
Long term I really wonder if the Tex rendering should not consult the non-Tex font selection mechanisms at all, and users should set the preamble by hand to get what they want. That would reduce confusion in my mind.

As commented here, one can turn the use of tex off for the ScalarFormatter such that the set font is used for the labels as well.
pharshalp commented on Jul 21, 2018
but then the tick labels won't be rendered using TeX (and other mathematical symbols, numbers will still be using TeX when text.usetex=True) which is inconsistent. When the user sets text.usetex = True the expected result is that all the fonts will be rendered using TeX. Hence, it would be better to ask the user to control the font by using text.latex.preamble.
ImportanceOfBeingErnest commented on Jul 21, 2018
The ticklabels do use tex, because text.usetex=True is set. But they are not rendered in math mode (i.e. the $ are removed). Hence they use the same font used by the rest of the document, but still through the tex system in use.

ahh right... that makes sense. But, this won't solve the issue if you have a mathematical formula in the title (or annotations) since it has to be rendered in math mode.

In this issue, there is no math mode text used. Hence this would solve this issue.
