如何在matplotlib中制作具有统计意义多星标注

import matplotlib.pyplot as plt
import numpy as np

np.random.seed(0)
data = np.random.normal(0, 1, 100)

plt.hist(data, bins=10, edgecolor='black')

mean = np.mean(data)
std = np.std(data)

plt.annotate('Mean', xy=(mean, 0), xytext=(mean, 10),
             arrowprops=dict(facecolor='black', arrowstyle='->'))
plt.annotate('1 Std', xy=(mean + std, 0), xytext=(mean + std, 10),
             arrowprops=dict(facecolor='black', arrowstyle='->'))
plt.annotate('-1 Std', xy=(mean - std, 0), xytext=(mean - std, 10),
             arrowprops=dict(facecolor='black', arrowstyle='->'))

plt.legend(['Data'])
plt.xlabel('Value')
plt.ylabel('Frequency')

plt.show()
