PySimpleGUI画动态图的代码？

以下是使用PySimpleGUI绘制动态图的示例代码：

import PySimpleGUI as sg
import random

# 定义GUI布局
layout = [[sg.Graph(canvas_size=(400, 400), graph_bottom_left=(0, 0), graph_top_right=(400, 400), background_color='white', key='graph')],
          [sg.Button('Start'), sg.Button('Stop'), sg.Exit()]]

# 创建GUI窗口
window = sg.Window('Animated Graph', layout)

# 初始化绘图数据
points = [(x, random.randint(0, 400)) for x in range(400)]
line = None

# 动态绘制
while True:
    event, values = window.read(timeout=100)
    if event in (sg.WIN_CLOSED, 'Exit'):
        break
    elif event == 'Start':
        line = window['graph'].draw_line(points, width=2, color='red')
    elif event == 'Stop':
        window['graph'].delete_figure(line)
        line = None
    if line:
        # 更新绘图数据
        points.pop(0)
        points.append((399, random.randint(0, 400)))
        # 重新绘制线条
        window['graph'].delete_figure(line)
        line = window['graph'].draw_line(points, width=2, color='red')
    # 刷新GUI窗口
    window.refresh()

# 关闭GUI窗口
window.close()

运行以上代码，会打开一个窗口，点击Start按钮可以开始绘制动态图，点击Stop按钮可以停止绘制，点击Exit按钮可以退出程序。在本例中，我们使用PySimpleGUI的Graph组件来绘制图形，并通过循环不断更新绘图数据，实现动态绘制的效果。
