Mathplotlib pandas-绘制平均线到散点图？

import matplotlib.pyplot as plt
import pandas as pd

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

plt.scatter(df['x'], df['y'])

mean_x = df['x'].mean()
mean_y = df['y'].mean()

plt.axhline(mean_y, color='r', linestyle='--')
plt.axvline(mean_x, color='r', linestyle='--')

plt.legend(['Scatter Plot', 'Mean Line'])
plt.xlabel('X')
plt.ylabel('Y')

plt.show()
