有没有可能把数字放在matplot直方图的顶部？

import matplotlib.pyplot as plt
import numpy as np

data = np.random.randn(1000)  # 创建随机数据
plt.hist(data, bins=30)  # 绘制直方图

n, bins, patches = plt.hist(data, bins=30)

max_height = max(n)
max_index = np.argmax(n)

plt.annotate(f'{max_height}', xy=(bins[max_index], max_height), xytext=(bins[max_index], max_height + 10),
             arrowprops=dict(facecolor='black', arrowstyle='->'), ha='center')

plt.show()
