如何用Matplotlib绘制叠加轴的生成器？

import matplotlib.pyplot as plt
import numpy as np

fig, ax1 = plt.subplots()

x = np.linspace(0, 10, 100)
y1 = np.sin(x)
ax1.plot(x, y1, 'b-', label='sin(x)')
ax1.set_xlabel('x')
ax1.set_ylabel('sin(x)', color='b')
ax1.tick_params('y', colors='b')

ax2 = ax1.twinx()
y2 = np.cos(x)
ax2.plot(x, y2, 'r--', label='cos(x)')
ax2.set_ylabel('cos(x)', color='r')
ax2.tick_params('y', colors='r')

lines = ax1.get_lines() + ax2.get_lines()
labels = [line.get_label() for line in lines]
ax1.legend(lines, labels, loc='upper right')
plt.title('Plot with Multiple Axes')

plt.show()
