对于我的大学项目，我正在使用python开发流量生成脚本。此流量生成脚本利用多处理模块以并发方式生成大量的http流量。我的脚本工作正常，现在我正在尝试使用wxpython构建一个用户友好的GUI来操作这些脚本的工作。我已经将这两个脚本分开了。在我的GUI脚本中，我已经导入了我的流量生成（工作）脚本，然后我调用它的函数（work.time_func（）或work.requests_func（））来在用户启动时运行多个过程。 GUI。到这里我的脚本运行正常。此外，在我的wxpython面板中，我附加了一个图表，该图表绘制了与流量生成脚本相关的一些数据（各种进程之间的共享列表）（work.rt（multiprocessing.Manager（）。list（）） - ＆gt;实际上是共享的所有流程之间的数据）。现在要绘制的数据长度（len（work.rt））高达1,00,00,000，但是我的GUI仅在绘制了大约2500个数据后挂起。这可能是什么问题？如何克服它？我正在使用centos 6.5。这是我的代码：

找到解决方案， 使用wx.calllater而不是动画图形，即不使用1000毫秒间隔时间的funcanimation，首先调用简单绘制画布的绘图函数，然后在该函数内提供wx.calllater，在每1000毫秒后调用自身 例如
main_function():
plot_function()
plot_function(self):
<plotting of graph>
wx.CallLater(1000,self.plot_function)
