在更改事件时从Slider调用Matplotlib函数动画时出现的问题

import matplotlib.pyplot as plt
from matplotlib.animation import FuncAnimation

fig, ax = plt.subplots()

def update(frame):
    # 更新图形的逻辑代码
    # ...
    # 重新绘制图形
    ax.clear()
    ax.plot(x, y)

ani = FuncAnimation(fig, update, frames=range(num_frames), interval=100)

plt.show()

from matplotlib.widgets import Slider

slider_ax = plt.axes([0.1, 0.05, 0.8, 0.03])
slider = Slider(slider_ax, 'Slider', 0, 1, valinit=0)

def slider_callback(value):
    # 更新动画的逻辑代码
    # ...
    # 重新绘制图形
    ax.clear()
    ax.plot(x, y)
    # 更新滑动条的值
    slider.set_val(value)

slider.on_changed(slider_callback)
