How to solve the problem that Chinese is not displayed when adding custom x and y scales?

Chinese display problem solved

Solution one:

Download Chinese fonts (in bold, look at the system version)

• Step 1: Download the  SimHei  font (or other fonts that support Chinese display will also work)

• Step 2: Install fonts

  • Under linux: copy fonts to usr/share/fonts:

    sudo cp ~/SimHei.ttf /usr/share/fonts/SimHei.ttf
    

  • Windows and Mac: double-click to install

• Step 3: Delete the cache file in ~/.matplotlib

  cd ~/.matplotlib
  rm -r *
  

• Step 4: Modify the configuration file matplotlibrc

  vi ~/.matplotlib/matplotlibrc
  

  Modify the content of the file to:

  font.family         : sans-serif
  font.sans-serif         : SimHei
  axes.unicode_minus  : False
  

 

Solution two:

Set matplotlibrc dynamically in the Python script, which can also avoid the trouble caused by changing the configuration file. The specific code is as follows:

from pylab import mpl
# 设置显示中文字体
mpl.rcParams["font.sans-serif"] = ["SimHei"]

Sometimes, after the font is changed, some characters in the coordinate axis cannot be displayed normally. At this time, you need to change the axes.unicode_minus parameter:

# 设置正常显示符号
mpl.rcParams["axes.unicode_minus"] = False
