1. 安装中文字体
一般系统自带wqy-microhei,其ttc文件位于/usr/share/fonts/truetype/wqy/wqy-microhei.ttc
2. 将ttc文件复制到python文件目录
sudo cp /usr/share/fonts/truetype/wqy/wqy-microhei.ttc ./
3. 在python文件中加上
# -*- coding: utf-8 -*- import os.path
from matplotlib.font_manager import FontProperties
zh_font = FontProperties(fname=os.path.abspath('wqy-microhei.ttc'))
import matplotlib.pyplot as plt
plt.title(u'中文', fontproperties=zh_font)
