如何在matplotlob直方图中标记存储箱(Python)

import numpy as np
import matplotlib.pyplot as plt

data = np.random.randn(1000)  # 生成随机数据集

plt.hist(data, bins=30)  # 绘制直方图，设置存储箱数量为30

plt.axvline(np.mean(data), color='red', linestyle='dashed', linewidth=1)  # 标记均值
plt.axvline(np.median(data), color='green', linestyle='dashed', linewidth=1)  # 标记中位数

plt.title('Histogram with Marked Bins')  # 添加标题
plt.xlabel('Data')  # 添加x轴标签
plt.ylabel('Frequency')  # 添加y轴标签

plt.show()
