Matplotlib not using latex font while text.usetex==True
提问by Dirklinux
I want to create labels to my plots with the latex computer modern font. However, the only way to persuade matplotlib to use the latex font is by inserting something like:
我想用乳胶计算机现代字体为我的图创建标签。但是，说服 matplotlib 使用乳胶字体的唯一方法是插入如下内容：
title(r'$\mathrm{test}$')
This is of course ridiculous, I tell latex to start math mode, and then exit math mode temporary to write the actual string. How do I make sure that all labels are rendered in latex, instead of just the formulas? And how do I make sure that this will be the default behaviour?
这当然很可笑，我告诉乳胶启动数学模式，然后暂时退出数学模式以写入实际字符串。我如何确保所有标签都以乳胶呈现，而不仅仅是公式？我如何确保这将成为默认行为？
A minimal working example is as follows:
一个最小的工作示例如下：
import matplotlib as mpl
import matplotlib.pyplot as plt
import numpy as np
# use latex for font rendering
mpl.rcParams['text.usetex'] = True
x = np.linspace(-50,50,100)
y = np.sin(x)**2/x
plt.plot(x,y)
plt.xlabel(r'$\mathrm{xlabel\;with\;\LaTeX\;font}$')
plt.ylabel(r'Not a latex font')
plt.show()
This gives the following result:
这给出了以下结果：
Here the x axis is how I want the labels to appear. How do I make sure that all labels appear like this without having to go to math mode and back again?
这里的 x 轴是我希望标签出现的方式。如何确保所有标签都像这样显示，而不必进入数学模式并再次返回？

The default Latex font is known as Computer Modern:
默认的 Latex 字体称为Computer Modern：
from matplotlib import rc
import matplotlib.pylab as plt
rc('font', **{'family': 'serif', 'serif': ['Computer Modern']})
rc('text', usetex=True)
x = plt.linspace(0,5)
plt.plot(x,plt.sin(x))
plt.ylabel(r"This is $\sin(x)$", size=20)
plt.show()

The marked answer can be enabled by default by changing a few lines in the matplotlibrcfile:
默认情况下，可以通过更改matplotlibrc文件中的几行来启用标记的答案：
text.usetex = True
font.family = serif
font.serif = cm

I am using matplotlib 1.3.1 on Mac OSX, add the following lines in matplotlibrcworks for me
我在 Mac OSX 上使用 matplotlib 1.3.1，在matplotlibrc我的作品中添加以下几行
text.usetex : True
font.family : serif
font.serif : cm
