python中用matplotlib库画图时,把中文设置为宋体,英文设置为Time New Roman,有时候还需要显示公式。设置方法如下:
1 import matplotlib.pyplot as plt 2 from matplotlib import rcParams 3 import numpy as np 4 5 config = { 6 "font.family":'serif', 7 "font.size": 18, 8 "mathtext.fontset":'stix', 9 "font.serif": ['SimSun'], 10 } 11 rcParams.update(config) 12 13 x = np.random.random((10,)) 14 15 16 plt.plot(x,label='随机数') 17 plt.title('中文:宋体 \n 英文:$\mathrm{Times \; New \; Roman}$ \n 公式: $\\alpha_i + \\beta_i = \\gamma^k$') 18 plt.xlabel('横坐标') 19 plt.ylabel('纵坐标') 20 plt.legend() 21 plt.yticks(fontproperties='Times New Roman', size=18) 22 plt.xticks(fontproperties='Times New Roman', size=18) 23 plt.show()
