一般来说，SimHei应该都是包含在内的，只需在画图时指定字体即可

如果检测不到可用中文字体，可以手动安装字体

检测matplotlib字体文件夹

In [3]:

mpl.matplotlib_fname()

Out[3]:

'c:\\users\\twang\\appdata\\local\\conda\\conda\\envs\\py36\\lib\\site-packages\\matplotlib\\mpl-data\\matplotlibrc'

字体文件夹应该位于和mpl-data同级的位置，下载中文字体后放入ttf文件夹内即可(尚未测试)

In [4]:

# 可选项

mpl.font_manager._rebuild() #reload一下

In [5]:

font_name = "SimHei"
# font_name = "KaiTi"
mpl.rcParams['font.family']= font_name # 指定字体，实际上相当于修改 matplotlibrc 文件　只不过这样做是暂时的　下次失效
mpl.rcParams['axes.unicode_minus']=False # 正确显示负号，防止变成方框

t = np.linspace(0, 2*np.pi, 1000, endpoint=False)
y = np.sin(t)
fig, ax = plt.subplots()

ax.set_xlabel(u"text for t轴")
ax.set_ylabel(u"text for y轴")
ax.set_title(u"t和y对应关系")
ax.plot(t,y)
plt.savefig("test.png", bbox_inches='tight', dpi = 1000)

plt.text(0.5, 0.5, s=u'测试')
plt.show()
