问当超过matplotlib中的范围时绘制线条或颜色区域

EN

import matplotlib.pyplot as plt
import numpy as np

#Define min and max line
minline = -10
maxline = 10

#Generate dummy plotting data
x = np.arange(0.0, 2, 0.01)
y1 = 25*np.sin(2*np.pi*x)-10
y2 = 30*np.sin(4*np.pi*x)-10
maxy=max(y1.max(),y2.max())
miny=min(y1.min(),y2.min())

fig, axs = plt.subplots(2,1)

#Plot dummy data
for ax in axs:
    ax.plot(x,y1,'b')
    ax.plot(x,y2,'g')

#Draw lines
axs[0].axhline(y=minline,color='r')
axs[0].axhline(y=maxline,color='r')

#Draw filled regions
axs[1].fill_between(x,minline,miny,color='r',alpha=0.3)
axs[1].fill_between(x,maxline,maxy,color='r',alpha=0.3)

plt.show()
