matplotlib 在绘图中插入TeX公式
示例
可以使用rc函数将TeX公式插入绘图中
importmatplotlib.pyplotas pltplt.rc(usetex = True)
或访问rcParams:
importmatplotlib.pyplotas pltparams = {'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 pltplt.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
