Tab errors in plot_any.py

[coffm049-2]

First of all, these scripts are absolutely amazingly useful!!! Thank you so much.

When running plot_any.py I faced an issue related to consistent use of tabs vs spacing particularly from lines 530 onward. I changed these tabs to spaces in my local branch and it worked. I however don't have push access to the repo, so I just wanted to notify you of this bug.
