How to set different font when plotting with matplotlib in python?

Set locally, for example set font for title:

  tfont = {'fontname':'Times New Roman'}
  plt.title('title',**tfont)

Set globally:

  import matplotlib.pyplot as plt
  plt.rcParams['font.family'] = 'Times New Roman'

If it works fine, that’s ok. If it return something like the following:

  findfont: Font family ['.....'] not found. Falling back to DejaVu Sans.

Then continue.

Check first:

Check if the expected font exists in the system:

  fc-list : family | sort

  fc-list -f '%{file}\n' | sort

  fc-list : lang=zh

  fc-list :lang=zh -f "%{family}\n" | sort | uniq

If needed, install fontconfig first.

Copy it to the fonts directory

  cp <font path> /usr/share/fonts/<somewhere>

re-generate font cache:
```
  sudo fc-cache -fv
```
If needed, install fontconfig first.

Precautiously backup first:

  cp -r ~/.cache/matplotlib <somewhere>

Normally, the matplotlib font cache will re-generate automatically. That’s it.
