我正在编写一个带有嵌入wxPython（2.8.10.1）GUI的matplotlib（1.3.1）图形的应用程序，用于分析光谱。我有一个NavigationToolbar2WxAgg，所以我可以平移和缩放图。
当我使用平移工具时，图形不会刷新...直到我手动调整整个窗口的大小，表面上是因为它会触发Canvas上的setSize调用，然后刷新它。
作为临时修复，我实现了一个50毫秒的计时器，我在其中调用self.Canvas.Refresh（）。非常不理想......
由于我刚刚熟悉wxPython，我不清楚我的事件管道在哪里被破坏，并想知道那里的任何向导是否可能知道我需要阅读哪些文档，或者我需要哪个事件/绑定学习。
非常感谢！
