如何使用pandas hist注释三模态历史图？

import pandas as pd
import matplotlib.pyplot as plt

# 读取数据集
data = pd.read_csv('data.csv')

# 绘制直方图
plt.hist(data['column_name'], bins=10)

# 找到三个峰值点
peak1 = data['column_name'].mode()[0]
peak2 = data['column_name'].mode()[1]
peak3 = data['column_name'].mode()[2]

# 添加注释
plt.annotate('Peak 1', xy=(peak1, 100), xytext=(peak1, 200),
             arrowprops=dict(facecolor='red', arrowstyle='->'))
plt.annotate('Peak 2', xy=(peak2, 150), xytext=(peak2, 250),
             arrowprops=dict(facecolor='blue', arrowstyle='->'))
plt.annotate('Peak 3', xy=(peak3, 200), xytext=(peak3, 300),
             arrowprops=dict(facecolor='green', arrowstyle='->'))

# 显示图形
plt.show()
