python制图汉语无法显示问题解决方式

介绍：解决python制图汉语无法显示问题

本文主要介绍了在python中制图时遇到汉语无法显示的问题，并提供了解决方法。可能会出现的问题包括汉字错码或无法显示等，主要是针对plt.title和plt.plot部分。

python制图汉语无法显示问题解决方式

解决方法

1. plt.title中文显示的解决

可以通过导入本地的字体来改变汉字的显示效果。

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

2. plt.plot中文显示的解决

与上面的方法类似，通过加入下列一行代码来实现汉字在plt.plot中的正常显示。

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

代码示例

from matplotlib import pyplot as plt
import matplotlib.pyplot as plt
from matplotlib.font_manager import FontProperties
from matplotlib.ticker import MultipleLocator,FormatStrFormatter

font_set=FontProperties(fname=r"c:windowsfontssimsun.ttc",size=15)
plt.rcParams['figure.figsize']=(12.0,8.0)
plt.rcParams['image.interpolation']='nearest'
plt.rcParams['image.cmap']='gray'
plt.rcParams['font.size']='16'

fig=plt.figure()
plt.rcParams.update(
{
'text.usetex':False,
'font.family':'stixgeneral',
'mathtext.fontset':'stix',
}
)
