How do I set axes so that when I zoom in the figure the values in the window remain static and don't change

So I have this image which was generated using the below code

Now when I zoom into the picture,the axes tend to change,what I want is that zooming in shouldn't have an effect on the overall layout.

Is there a way to fix this

Enclosed are the original figure and the zoomed in figure

And here is the code similar to

And then the one with my changes
