设置matplotlib画图支持中文显示

1.安装中文字体

git clone https://github.com/tracyone/program_font && cd program_font && ./install.sh

2.拷贝ttf字体文件到matplotlib字体库

cp /usr/share/fonts/MyFonts/*.ttf /usr/share/matplotlib/mpl-data/fonts/ttf/

3.删除matplotlib缓存列表

rm -r ~/.cache/matplotlib

4.设置中文代码

#画图前调用set_matplot_zh_font()即可显示中文
# -*- coding: utf-8 -*-
import matplotlib.pyplot as plt
from matplotlib.font_manager import FontManager
from pylab import mpl
import subprocess
def get_matplot_zh_font():
    fm = FontManager()
    mat_fonts = set(f.name for f in fm.ttflist)
    output = subprocess.check_output('fc-list :lang=zh -f "%{family}\n"',sh$
    output = output.decode('utf-8')
    zh_fonts = set(f.split(',',1)[0] for f in output.split('\n'))
    available = list(mat_fonts & zh_fonts)

    print '*' * 10,'可用字体','*' * 10
    for f in available:
        print f
    return available
def set_matplot_zh_font():
    available = get_matplot_zh_font()
    if len(available) > 0:
            mpl.rcParams['font.sans-serif'] = [available[0]]
            mpl.rcParams['axes.unicode_minus'] = False
