我已经为此苦苦挣扎了几天。如果我不使用 wx.Notebook,我可以让 FigureCanvas 在 sizer 中正确调整大小,但是一旦我将 FigureCanvas 放在 wx.Notebook 面板中,绘图似乎会忽略面板大小调整器。它也有某种刷新问题,如果你把它从屏幕上拉下来再打开,情节就消失了。也许命令的顺序有问题,但我似乎找不到。这篇文章:How to update a plot with python and Matplotlib帮助我做到了这一点,但我似乎无法弄清楚为什么一旦我在 wx.Notebook 中使用它时,情节的表现会有所不同。
这是它首次显示时的样子:http: //static.inky.ws/image/2205/image.jpg
这是在我中途关闭屏幕之后:http: //static.inky.ws/image/2206/image.jpg
