1、导入模块:import matplotlib.pyplot as plt2、定义图像窗口:plt.figure()3、画图:plt.plot(x, y)4、定义坐标轴范围:x轴:plt.xlim()/y轴:plt.ylim() lim其实就是limit的缩写5、定义坐标轴名称:x轴:plt.xlabel()/plt.ylabel()6、定义坐标轴刻度及名称:plt.xticks()/plt.yticks()7、设置图像边框颜色...
Add Legend Outside:By using thelegend()method we can add a legend to a plot. To specify it outside the plot use thebbox_to_anchorattribute of thelegend()function. Generate a Plot:Use theshow()method to visualize the plot on the user’s windows. ...
→ ax.legend(frameon=False) … show error as shaded region? → ax.fill_between(X, Y+error, Y‐error) … draw a rectangle? → ax.add_patch(plt.Rectangle((0, 0),1,1) … draw a vertical line? → ax.axvline(x=0.5) … draw outside frame? → ax.plot(…, clip_on=False) …...

使用fig.add_subplot方法创建子图,其中nrows和ncols表示子图的行数和列数,index表示当前子图的位置编号。二、进阶技巧 图表美化:添加轴标签:使用plt.xlabel和plt.ylabel。添加图例:使用plt.legend。调整刻度线和颜色:使用plt.xticks、plt.yticks以及颜色参数。显示中文:配置字体文件,确保matplotlib能...
