Matplotlib 如何显示中文

Python 3.x

主要是如下代码

import os
font = FontProperties(fname=os.path.expandvars(r"%windir%\fonts\simsun.ttc"), size=14)
plt.xlabel("测试", fontproperties=font)

# coding:utf-8
# from __future__ import unicode_literals #Python 3.x 不需要此行
from matplotlib.font_manager import FontProperties
import matplotlib.pyplot as plt
import os
font = FontProperties(fname=os.path.expandvars(r"%windir%\fonts\simsun.ttc"), size=14)
from numpy import *
import operator
__author__ = 'norsd@163.com'

def run_helper():
    import matplotlib
    import matplotlib.pyplot as plt
    fig = plt.figure()
    plt.xlabel("测试", fontproperties=font)
    plt.ylabel("ABC")
    ax = fig.add_subplot(111)
    ax.scatter(a[:, 0], a[:, 1], 15.0*array(b), 15.0*array(b))
    plt.show()
if __name__ == '__main__':
    run_helper()
