jupyter中matplotlib画图无法显示中文的问题

一、查看已安装的中文字体库

import subprocess
mpl_fonts = set(f.name for f in FontManager().ttflist)
output = subprocess.check_output('fc-list :lang=zh -f "%{family}\n"', shell=True)
output = output.decode('utf-8')
zh_fonts = set(f.split(',', 1)[0] for f in output.split('\n'))
available = zh_fonts & mpl_fonts
print(available)

{'WenQuanYi Micro Hei', 'WenQuanYi Zen Hei', 'AR PL UMing CN'}

二、在画图中设置

plt.rc("font", family="WenQuanYi Zen Hei")
