PR Summary

This is an experiment to address and discuss #20595

Note that dddot and ddddot were already defined as 8411 and 8412 in tex2uni in _mathtext_data.py, I added them again as combiningthreedotsabove and combiningfourdotsabove.

This PR also added a --keep-going flag in make.bat so I could build the documentation on Windows. I should probably raise that in a separate issue/PR.

Before, Mathtext Mode

After, Mathtext Mode

LaTeX vs. Mathtext Tests

With the right packages included, this works fine with usetex=True:

import matplotlib.pyplot as plt
import matplotlib as mpl
plt.rc('text.latex', preamble=r'\usepackage{amsmath}\usepackage{amssymb}')

fig = plt.figure(figsize=(15, 9), dpi=200)
ax = fig.subplots(1, 1)
fs = 80

pstra = r'$\dot{x}\hspace{1.5}\ddot{x}\hspace{1.5}\dddot{x}\hspace{1.5}\ddddot{x}$'
pstratex = r'$\dot{x}\hspace{1.5em}\ddot{x}\hspace{1.5em}\dddot{x}\hspace{1.5em}\ddddot{x}$'

ax.annotate(pstra, xy=(0.1, 0.1), fontsize=fs)
ax.annotate(pstratex, xy=(0.1, 0.5), fontsize=fs, usetex=True)
ax.plot([0, 1], [0.591]*2, linewidth=0.5)
ax.plot([0, 1], [0.221]*2, linewidth=0.5)
ax.set_ylim([-0.1, 1])
ax.set_xlim([0, 1])
fig.tight_layout()

usetex=True on the top, Mathtext mode on the bottom:
