可以使用rc函数将TeX公式插入绘图中
importmatplotlib.pyplotas plt plt.rc(usetex = True)
或访问rcParams：
importmatplotlib.pyplotas plt
params = {'tex.usetex': True}
plt.rcParams.update(params)TeX\对命令和符号使用反斜杠，这可能与Python字符串中的特殊字符冲突。为了在Python字符串中使用文字反斜杠，必须对它们进行转义或将其合并到原始字符串中：
plt.xlabel('\\alpha')
plt.xlabel(r'\alpha')下图可以通过代码生成
importmatplotlib.pyplotas plt plt.rc(usetex = True) x = range(0,10) y = [t**2 for t in x] z = [t**2+1 for t in x] plt.plot(x, y, label = r'$\beta=\alpha^2$') plt.plot(x, z, label = r'$\beta=\alpha^2+1$') plt.xlabel(r'$\alpha$') plt.ylabel(r'$\beta$') plt.legend(loc=0) plt.show()
不支持显示的方程式（例如$$...$$或\begin{equation}...\end{equation}）。不过，使用可以显示数学样式\displaystyle。
要加载乳胶包装，请使用以下tex.latex.preamble参数：
params = {'text.latex.preamble' : [r'\usepackage{siunitx}', r'\usepackage{amsmath}']}
plt.rcParams.update(params)但是请注意，示例matplotlibrc文件中的警告：
#text.latex.preamble : # IMPROPER USE OF THIS FEATURE WILL LEAD TO LATEX FAILURES
# AND IS THEREFORE UNSUPPORTED. PLEASE DO NOT ASK FOR HELP
# IF THIS FEATURE DOES NOT DO WHAT YOU EXPECT IT TO.
# preamble is a comma separated list of LaTeX statements
# that are included in the LaTeX document preamble.
# An example:
# text.latex.preamble : \usepackage{bm},\usepackage{euler}
# The following packages are always loaded with usetex, so
# beware of package collisions: color, geometry, graphicx,
# type1cm, textcomp. Adobe Postscript (PSSNFS) font packages
# may also be loaded, depending on your font settings
