代码的第一部分正在工作，即绘制文件。只有当我试图绘制缩放部分，它给出了以下错误，我试图找出它，但没有一个帖子真的有用。

I am trying to do a zoomed in inset plot like the image:
The first part of the code is working i.e. it is plotting the file. Only when I try to plot the zoomed part it gives the following error I have trying to figure it out but none of the posts have been really helpful.
AttributeError Traceback (most recent call last)
