How to change fonts in matplotlib (python)?
提问by SirC
It sounds as an easy problem but I do not find any effective solution to change the font (not the font size) in a plot made with matplotlib in python.
这听起来是一个简单的问题，但我没有找到任何有效的解决方案来在 python 中使用 matplotlib 制作的图中更改字体（而不是字体大小）。
I found a couple of tutorials to change the default font of matplotlib by modifying some files in the folders where matplotlib stores its default font - see this blog post- but I am looking for a less radical solution since I would like to use more than one font in my plot (text, label, axis label, etc).
我找到了一些教程，通过修改 matplotlib 存储其默认字体的文件夹中的一些文件来更改 matplotlib 的默认字体 - 请参阅此博客文章- 但我正在寻找一个不太激进的解决方案，因为我想使用多个我的图中的字体（文本、标签、轴标签等）。

Say you want Comic Sans for the title and Helvetica for the x label.
假设标题需要 Comic Sans，x 标签需要 Helvetica。
csfont = {'fontname':'Comic Sans MS'}
hfont = {'fontname':'Helvetica'}
plt.title('title',**csfont)
plt.xlabel('xlabel', **hfont)
plt.show()

或者
import matplotlib.pyplot as mpl

I prefer to employ:
我更喜欢雇用：
from matplotlib import rc
#rc('font',**{'family':'sans-serif','sans-serif':['Helvetica']})
rc('font',**{'family':'serif','serif':['Times']})
rc('text', usetex=True)

The Helvetica font does not come included with Windows, so to use it you must download it as a .ttf file. Then you can refer matplotlib to it like this (replace "crm10.ttf" with your file):
Helvetica 字体不包含在 Windows 中，因此要使用它，您必须将其下载为 .ttf 文件。然后你可以像这样引用 matplotlib（用你的文件替换“crm10.ttf”）：
import os
from matplotlib import font_manager as fm, rcParams
import matplotlib.pyplot as plt
fig, ax = plt.subplots()
fpath = os.path.join(rcParams["datapath"], "fonts/ttf/cmr10.ttf")
prop = fm.FontProperties(fname=fpath)
fname = os.path.split(fpath)[1]
ax.set_title('This is a special font: {}'.format(fname), fontproperties=prop)
ax.set_xlabel('This is the default font')
plt.show()
print(fpath)will show you where you should put the .ttf.
print(fpath)会告诉你应该把 .ttf 放在哪里。
