matplotlib - wxpython后端-快速更新

import matplotlib.pyplot as plt
import wx

app = wx.App()
frame = wx.Frame(None, title="Matplotlib with wxPython")
panel = wx.Panel(frame)

figure = plt.figure()
canvas = FigureCanvas(panel, -1, figure)
sizer = wx.BoxSizer(wx.VERTICAL)
sizer.Add(canvas, 1, wx.EXPAND)
panel.SetSizer(sizer)

def update_plot():
    # 更新图形内容的代码
    # 可以通过修改图形对象的属性或重新绘制图形来实现更新
    # 例如：figure.clear() 清空图形内容
    #       ax = figure.add_subplot(111) 添加一个子图
    #       ax.plot(x, y) 绘制新的曲线
    #       canvas.draw() 重新绘制图形

timer = wx.Timer(frame)
frame.Bind(wx.EVT_TIMER, lambda event: update_plot(), timer)
timer.Start(1000)  # 每隔1秒更新一次图形

frame.Show()
app.MainLoop()
