前言

python画图，如果用英文显示基本没有问题，但是中文可能会有乱码或者不显示的情况。

经过个人的测试，下图中“横轴”，“纵轴”字样的中文显示没有什么大问题，主要是plt.title部分和plt.plot部分的显示

一、plt.title中文显示的解决：

from matplotlib.font_manager import FontProperties
font_set = FontProperties(fname=r"c:\windows\fonts\SIMLI.TTF", size=15)
plt.title(u'小明的标题', FontProperties=font_set)

FontProperties中加载的就是本地的字体

路径：C:\Windows\Fonts

选中字体鼠标右键属性即可复制名字进行替换

font_set = FontProperties(fname=r"c:\windows\fonts\SIMLI.TTF", size=15)

从改变字体的结果来看，横纵坐标和标题区域受影响，plt.plot不受影响

二、plt.plot中文显示的解决：

与上述类似，加下列一行即可

plt.legend(prop={'family':'SimHei','size':15})

三、供参考代码

from matplotlib import pyplot
import matplotlib.pyplot as plt
from matplotlib.font_manager import FontProperties
from matplotlib.ticker import MultipleLocator, FormatStrFormatter
font_set = FontProperties(fname=r"c:\windows\fonts\simsun.ttc", size=15)
import matplotlib
import numpy as np
%matplotlib inline

plt.rcParams['figure.figsize'] = (12.0, 8.0) # set default size of plots
plt.rcParams['image.interpolation'] = 'nearest'
plt.rcParams['image.cmap'] = 'gray'
# plt.rcParams['font.sans-serif']=['SimHei']
# plt.rcParams['axes.unicode_minus']=False
# 设置标题大小
plt.rcParams['font.size'] = '16'

fig = plt.figure()
matplotlib.rcParams.update(
{
'text.usetex': False,
'font.family': 'stixgeneral',
'mathtext.fontset': 'stix',
}
)
# myfont = FontProperties(fname='/homenuxidc/.local/fonts/文泉驿正黑.ttf')

x = range(0,102,2)

x = [str(x) for x in list(x)]

x = range(len(x))

#这里如果取得值，最好省略，否则冗余代码太多

plt.plot(x, dj1,marker='s',label=u'小明')

plt.grid(linestyle='--')
plt.grid(axis="x")
plt.title(u'SimHei', fontproperties=font_set)
plt.title('小明的标题')
plt.legend()  # 让图例生效

y_major_locator=MultipleLocator(0.1)

ax=plt.gca()
ax.yaxis.set_major_locator(y_major_locator)
plt.ylim(0,1)

plt.xlim(0,55)

plt.margins(0)
plt.subplots_adjust(bottom=0.001)

plt.xlabel("横轴",fontproperties=font_set) #X轴标签
plt.ylabel("纵轴",fontproperties=font_set) #Y轴标签
plt.legend(prop={'family':'SimHei','size':15})
