When I set AX.ticklabel_format(useMathText=True), and save as a PGF plot, it gets stuck later when compiling with pdflatex, saying:
! Missing } inserted
<inserted text>
}
l.277 ...selectfont \(\displaystyle \times{10^{−
1}}{}\)}%
! Extra }, or forgotten $.
l.277 ...lectfont \(\displaystyle \times{10^{−1}
}{}\)}%
A minimum (not)working example is as follows. Uncomment all the commented lines in order to save a PGF file.
#import matplotlib as mpl
import matplotlib.pyplot as plt
import numpy as np
#mpl.use("pgf")
#PGF_WITH_RC_FONTS = {
# "font.family": "serif",
# "font.serif": [],
# "font.sans-serif": [],
#}
#mpl.rcParams.update(PGF_WITH_RC_FONTS)
FIG, AXES = plt.subplots(constrained_layout=True)
X = np.linspace(0.0001, 0.001, 10)
AXES.plot(X, X)
AXES.tick_params(direction='in', length=9, labelsize=15)
AXES.tick_params(which='minor', direction='in')
AXES.ticklabel_format(style='sci', scilimits=(0, 1), useMathText=True)
#plt.savefig('matplotlib_useMathText.pgf', bbox_inches='tight')
plt.show()
The images produced in the PDF (upon skipping through the errors in pdflatex), compared against what one may see normally:
As you can see, the “10^{-3}” is not rendered correctly in the case of the PDF derived from the PGF. The latex code that generates the pdf using pdflatex is as follows:
\documentclass{standalone}
\usepackage{amsmath,amssymb}
\usepackage[T1]{fontenc}
\usepackage[utf8]{inputenc}
\usepackage{lmodern}
\usepackage{pgf}
\DeclareUnicodeCharacter{2212}{$-$}
