通过pandas数据框创建的图形的两条线之间的不同颜色进行着色

import pandas as pd
import matplotlib.pyplot as plt

data = {'x': [1, 2, 3, 4, 5],
        'y1': [2, 4, 6, 8, 10],
        'y2': [1, 3, 5, 7, 9]}
df = pd.DataFrame(data)

plt.plot(df['x'], df['y1'], color='blue', label='Line 1')
plt.plot(df['x'], df['y2'], color='green', label='Line 2')
plt.fill_between(df['x'], df['y1'], df['y2'], where=(df['y1'] > df['y2']), color='yellow', alpha=0.3)
plt.fill_between(df['x'], df['y1'], df['y2'], where=(df['y1'] < df['y2']), color='red', alpha=0.3)
plt.legend()
plt.show()
