这是我的第一个python项目，我试图在Matplotlib中绘制Mandelbrot集并将其放入tkinter框架中。这已经完成，但是随着GUI一起出现无关的空白图形。这个空的图有正确数量的刻度标记，而图中的绘图在绘图上有不正确数量的刻度标记（我不能确定刻度值来自哪里，但我怀疑是像素）。我现在也搜索了一段时间，如何解决这个问题无济于事。我尝试过canvas.draw，弄乱了方法和类，但我仍然无法弄清楚......以下是将运行的代码的摘录。指定显示的代码位于名为mandelbrot_image的方法中，并且MainPage类 预先感谢您。外来的Matplotlib图（tkinter中的图）

（不涉及接受答案） 我也想知道我怎么能添加标准工具栏到情节。就像我尝试添加它，但它只显示在多余的matplotlib图中，而不是GUI中的图 – Simon
还没有为您提供[答案]（http://stackoverflow.com/a/42483817/4124317）解决了两个数字出现的问题？你之间有什么变化？ – ImportanceOfBeingErnest
您提供的答案将该图插入到tkinter画布中（我很感激）。第二个数字伴随着解决方案。 – Simon
