python画图中文无法显示

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 FontProperties中加载的就是本地的字体 路径：C:\Windows\Fonts
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 dj1=[0.140885022563663,0.285128051316358,0.331236115292078,0.372582750937596,0.463174450139405,0.586773503380428,0.542598182149781,0.542598182149781,0.564956686389027,0.542598182149781,0.519630577568173,0.428649426296771,0.676284101462148,0.635875231620977,0.564956686389027,0.542598182149781,0.564956686389027,0.62899995822798,0.676284101462148,0.721874028834649,0.676284101462148,0.702515362688485,0.682890636232397,0.557567115066442,0.564956686389027,0.635875231620977,0.656252254277025,0.676284101462148,0.721874028834649,0.62899995822798,0.62899995822798,0.702515362688485,0.759939881400332,0.702515362688485,0.696005029828444,0.656252254277025,0.696005029828444,0.676284101462148,0.608105164606941,0.741002175030875,0.721874028834649,0.702515362688485,0.721874028834649,0.62899995822798,0.608105164606941,0.682890636232397,0.676284101462148,0.702515362688485,0.696005029828444,0.696005029828444,0.696005029828444] 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}) |
选中字体鼠标右键属性即可复制名字进行替换
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【本文地址】
