填充交叉区域
填充两条曲线之间的区域。
import matplotlib.pyplot as plt
import numpy as np
x = np.arange(-5, 5, 0.01)
y1 = -5*x*x + x + 10
y2 = 5*x*x + x
fig, ax = plt.subplots()
ax.plot(x, y1, x, y2, color='black')
ax.fill_between(x, y1, y2, where=y2 >y1, facecolor='yellow', alpha=0.5)
ax.fill_between(x, y1, y2, where=y2 <=y1, facecolor='red', alpha=0.5)
ax.set_title('Fill Between')
plt.show()
