使用python从交互式图表中提取数据点？

import matplotlib.pyplot as plt
import numpy as np

x = np.linspace(0, 10, 100)
y = np.sin(x)

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

def onclick(event):
    if event.xdata and event.ydata:
        print(f"Clicked at x = {event.xdata:.2f}, y = {event.ydata:.2f}")

fig.canvas.mpl_connect('button_press_event', onclick)

import matplotlib.pyplot as plt
import numpy as np

def onclick(event):
    if event.xdata and event.ydata:
        print(f"Clicked at x = {event.xdata:.2f}, y = {event.ydata:.2f}")

x = np.linspace(0, 10, 100)
y = np.sin(x)

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

fig.canvas.mpl_connect('button_press_event', onclick)

plt.show()
