Matplotlib在tkinter中起作用

Question

这是我的第一个python项目，所以我明白这个问题可能看起来有点愚蠢。我正在尝试创建一个Mandelbrot渲染器。我正在从我理解的教程和代码中拼凑代码来制作一些东西。所以基本上我有渲染器的GUI的所有数学和基本功能，但我无法让matplotlib图实际在tkinter GUI中绘图。 matplolib显示部分实际上是一个需要运行mandelbrot_image(-0.8,-0.7,0,0.1,cmap='hot')的函数。如果引入了该代码，则绘制Mandelbrot集，但是在不同的matplotlib窗口中。

这是我的所有代码，我提前感谢你，我再一次道歉。
