# 1. before use this script, you need to get a customed ttf font file, maybe you have only ttc file ,you can convert it to ttf in
# this awesome web: http://www.zhuan-huan.com/file-convert/
# 2. then edit the matplotlibrc file(for env most in envs/py3/lib/python3.5/site-packages/matplotlib/mpl-data ), uncomment two lines:
# font.family : sans-serif
# font.sans-serif :WenQuanYi Zen Hei,Bitstream Vera Sans, Lucida Grande, Verdana, Geneva, Lucid...
# if your ttf font is sans-serif,you need only to add your new font name to the head of font.sans-serif.
import matplotlib as mpl
import matplotlib.pyplot as plt
import matplotlib.font_manager as font_manager
path = '/home/june/anaconda2/envs/py3/lib/python3.5/site-packages/matplotlib/mpl-data/fonts/ttf/wqy_zenhei.ttf'
prop = font_manager.FontProperties(fname=path)
print(prop.get_family())
print(prop.get_name())
# if you want to dynamic change font in code, you can step over step 2 above and copy fellow lines code to your work.
mpl.rcParams['font.family'] = prop.get_name()
# here is example.
fig, ax = plt.subplots()
ax.set_title('中国是个美丽的国家', size=40)
plt.show()
