The font of the axis tick mark labels produced from the following code isn't Helvetica, but is still the default serif Computer Modern. Any suggestions are greatly appreciated.
from matplotlib import rc, font_manager
from numpy import arange, cos, pi
from matplotlib.pyplot import figure, axes, plot, xlabel, ylabel, title, \
grid, savefig, show
sizeOfFont = 12
fontProperties = {'family':'sans-serif','sans-serif':['Helvetica'],
'weight' : 'normal', 'size' : sizeOfFont}
ticks_font = font_manager.FontProperties(family='Helvetica', style='normal',
size=sizeOfFont, weight='normal', stretch='normal')
rc('text', usetex=True)
rc('font',**fontProperties)
figure(1, figsize=(6,4))
ax = axes([0.1, 0.1, 0.8, 0.7])
t = arange(0.0, 1.0+0.01, 0.01)
s = cos(2*2*pi*t)+2
plot(t, s)
for label in ax.get_xticklabels():
label.set_fontproperties(ticks_font)
for label in ax.get_yticklabels():
label.set_fontproperties(ticks_font)
xlabel(r'\textbf{time (s)}')
ylabel(r'\textit{voltage (mV)}',fontsize=16,family='Helvetica')
title(r"\TeX\ is Number $\displaystyle\sum_{n=1}^\infty\frac{-e^{i\pi}}{2^n}$!",
fontsize=16, color='r')
grid(True)
savefig('tex_demo.pdf')
show()
Okay, this worked for me. Replace the following lines:
for label in ax.get_xticklabels():
label.set_fontproperties(ticks_font)
for label in ax.get_yticklabels():
label.set_fontproperties(ticks_font)
with this:
from matplotlib.pyplot import gca
a = gca()
a.set_xticklabels(a.get_xticks(), fontProperties)
a.set_yticklabels(a.get_yticks(), fontProperties)
What you did in your original code makes sense to me, but I get different results this way. Weird.
