如何在Matplotlib中创建自定义鼠标光标

import matplotlib.pyplot as plt
import numpy as np

# 创建一个自定义鼠标光标
class CustomCursor(plt.backend_bases.Cursor):
    def __init__(self, useblit=True, **kwargs):
        super().__init__(useblit=useblit, **kwargs)

    def draw(self, renderer):
        # 在这里定义自定义光标的样式和形状
        pass

# 创建一个简单的图形
x = np.linspace(0, 10, 100)
y = np.sin(x)

fig, ax = plt.subplots()
ax.plot(x, y)

# 将自定义光标应用到图形上
cursor = CustomCursor()
ax.add_cursor(cursor)

plt.show()
