在Matplotlib中使用右轴和左轴绘制条形图和线条

import matplotlib.pyplot as plt
import numpy as np

x = np.array([1, 2, 3, 4, 5])
y1 = np.array([10, 20, 30, 40, 50])
y2 = np.array([1, 4, 9, 16, 25])

fig, ax1 = plt.subplots()

ax1.bar(x, y1, color='blue')

ax2 = ax1.twinx()

ax2.plot(x, y2, color='red')

ax1.set_xlabel('X轴')
ax1.set_ylabel('左轴')
ax2.set_ylabel('右轴')
ax1.legend(['左轴'], loc='upper left')
ax2.legend(['右轴'], loc='upper right')

plt.show()
