我们有没有办法用matplotlib标记boxplot中的图？

import matplotlib.pyplot as plt
import numpy as np

data = [np.random.normal(0, std, 100) for std in range(1, 4)]

plt.boxplot(data)

plt.annotate('标记', xy=(x, y), xytext=(x_text, y_text),
             arrowprops=dict(arrowstyle='->'))

import matplotlib.pyplot as plt
import numpy as np

data = [np.random.normal(0, std, 100) for std in range(1, 4)]

plt.boxplot(data)

# 添加标记
plt.annotate('标记', xy=(x, y), xytext=(x_text, y_text),
             arrowprops=dict(arrowstyle='->'))

plt.show()
