在代码钱加入：
config = { "font.family": 'serif', "font.size": 10.5, "mathtext.fontset": 'stix', "font.serif": ['SimSun'], }rcParams.update(config)%config InlineBackend.figure_format = 'retina'%matplotlib inlineimport numpy as npimport mathimport matplotlib.pyplot as pltfrom matplotlib import rcParamsconfig = { "font.family": 'serif', "font.size": 10.5, "mathtext.fontset": 'stix', "font.serif": ['SimSun'], }rcParams.update(config)x=[1,2,3]y=[1,2,3]plt.plot(x, y,label="时间随着距离的变换参数：y=0.5*x")plt.xlabel('时间参数/s')plt.ylabel('距离参数/v)')plt.legend() # 显示图例plt.show()
一、设置图像x、y两轴及文本标签内容整体和斜体，和mathtype格式一样
mathit：斜体mathrm：正体1.1 图中标签正斜体
%config InlineBackend.figure_format = 'retina'%matplotlib inlineimport numpy as npimport mathimport matplotlib.pyplot as pltfrom matplotlib import rcParamsconfig = { "font.family": 'serif', "font.size": 10.5, "mathtext.fontset": 'stix', "font.serif": ['SimSun'], }rcParams.update(config)x=[1,2,3]y=[1,2,3]#plt.plot(x, y,label="时间随着距离的变换参数：y=0.5*x")plt.plot(x, y, label=r'$\mathit{label}_{\mathrm{sub}}$')plt.xlabel('时间参数/s')plt.ylabel('距离参数/v)')plt.legend() # 显示图例plt.show()
1.2 x、y轴正斜体
这里先介绍怎么同时设置上下标，看代码照着做即可
%config InlineBackend.figure_format = 'retina'%matplotlib inlineimport numpy as npimport mathimport matplotlib.pyplot as pltfrom matplotlib import rcParamsconfig = { "font.family": 'serif', "font.size": 10.5, "mathtext.fontset": 'stix', "font.serif": ['SimSun'], }rcParams.update(config)x=[1,2,3]y=[1,2,3]plt.plot(x, y,label="时间随着距离的变换参数：y=0.5*x")plt.plot(x, y, label=r'$\mathit{label}_{\mathrm{sub}}$')plt.xlabel('Time (s)')plt.ylabel('Force ($\mathregular{F_{net}^{max}}$)')plt.legend() # 显示图例plt.show()
其次，上下标正斜体的设置，比如说把上图net设置为斜体：
%config InlineBackend.figure_format = 'retina'%matplotlib inlineimport numpy as npimport mathimport matplotlib.pyplot as pltfrom matplotlib import rcParamsconfig = { "font.family": 'serif', "font.size": 10.5, "mathtext.fontset": 'stix', "font.serif": ['SimSun'], }rcParams.update(config)x=[1,2,3]y=[1,2,3]plt.plot(x, y)plt.xlabel('Time (s)')plt.ylabel('Force ($\mathregular{F_{\mathit{net}}^{max}}$)')plt.show()
其次，上下标正斜体的设置，比如说把上图net改为整体、F改为斜体：
%config InlineBackend.figure_format = 'retina'%matplotlib inlineimport numpy as npimport mathimport matplotlib.pyplot as pltfrom matplotlib import rcParamsconfig = { "font.family": 'serif', "font.size": 10.5, "mathtext.fontset": 'stix', "font.serif": ['SimSun'], }rcParams.update(config)x=[1,2,3]y=[1,2,3]plt.plot(x, y)plt.xlabel('Time (s)')plt.ylabel('Force ($\mathregular{\mathit{F}_{net}^{max}}$)')plt.show()
