How to zoomed a portion of image and insert in the same plot in matplotlib

Question

I would like to zoom a portion of data/image and plot it inside the same figure. It looks something like this figure.

Answer 1

The nicest way I know of to do this is to use mpl_toolkits.axes_grid1.inset_locator (part of matplotlib).

There is a great example with source code here: https://github.com/NelleV/jhepc/tree/master/2013/entry10
