I am trying to use different math font sets for two axes in the same figure, with no success. I have searched this issue using google and I have read the matplotlib's official guide on how to use the math font. But I can not find ways to achieve this effect. My complete code is as follows:
import matplotlib.pyplot as plt
import matplotlib as mpl
fig, (ax1, ax2) = plt.subplots(ncols=2)
mpl.rcParams['mathtext.fontset'] = 'cm' # use font "cm" for first axes
ax1.text(0.3, 0.5, r"$xyz$", fontsize=50)
ax1.set_title('before')
ax1.axis('off')
ax1.set_aspect('equal')
mpl.rcParams['mathtext.fontset'] = 'stixsans' # use font "stixsans" for second axes
ax2.text(0.3, 0.5, r"$xyz$", fontsize=50)
ax2.set_title('after')
ax2.axis('off'）
ax2.set_aspect('equal')
plt.show()
The resulting figure shows that both the axes use the "stixsans" font, see picture here.
It seems that mpl.rcParams['mathtext.fontset'] = 'stixsans' in the later part has overruled the previous setting mpl.rcParams['mathtext.fontset'] = 'cm'. Any idea how to prevent this from happening and use "cm" and "stixsans" font for the two axes respectively?
