我想知道如何在Python中嵌入一個wxPython的FigureCanvasWxAgg實例的內部matplotlib人物時可以執行下列僞代碼：與畫布到數字的wxPython
以下項目需要使用：
- - - - 可以採用進口- - - -
進口WX
從matplotlib.figure導入圖
從matplotlib.backends.backend_wxagg進口FigureCanvasWxAgg作爲FigureCanvas
- - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - -
main_canvas;
shadow_canvas;
big_plot [一個matplotlib圖形實例，其中有一個大的陰謀 - 就像你會用figure.add_subplots（1,1,1）]所做的那樣;
small_subplots [有，比如說一個matplotlib圖實例2個次要情節在裏面 - 你會作出與人物。add_subplots（2,1，i），其中1 < = I < = 2]
被叫SwapView（main_canvas，shadow_canvas，big_plot，small_subplots）函數基本上交換圖中當前正在shadow_canvas與一個在main_canvas（所以保持一個有一個大陰謀和一個有許多小地塊之間切換））
功能UpdateDisplay（即每次調用SwapView時間（）動態地更新顯示
******* PSEUDOCODE ******* main_canvas.show() shadow_canvas.hide() main_canvas has big_plot initially shadow_canvas has small_subplots initially if big_plot in main_canvas: SwapView(...) ---> should put big_plot in shadow_canvas and small_subplots in the main_canvas else: SwapView(...) ---> should put the small_subplots in shadow_canvas and the big_plot in main_canvas UpdateDisplay() ******* END OF CODE *******
這是我在這段代碼的初始嘗試，不幸的是我找不到找到當前顯示哪個圖的方法。
