如何在matplotlib上将两个不同的熊猫数据框绘制成一个图表？

import pandas as pd
import matplotlib.pyplot as plt

df1 = pd.DataFrame({'x': [1, 2, 3, 4, 5], 'y': [10, 20, 30, 40, 50]})
df2 = pd.DataFrame({'x': [1, 2, 3, 4, 5], 'y': [5, 10, 15, 20, 25]})

fig, ax = plt.subplots()

ax.plot(df1['x'], df1['y'], label='Data Frame 1')

ax.plot(df2['x'], df2['y'], label='Data Frame 2')

ax.legend()

plt.show()
