I solved the problem by using animation class. If was a bit tricky, as I had inner loops that also were producing plots for same sequence, and from what I understood about this class, iterator is "frames" argument in FuncAnimation() function, which also returns the frame, so you may imagine how I solved inner loops.
I guess there is instrumentation for such case, but documentation about animation class is beyond my comprehension. Also couple of blogs explaining basics of FuncAnimation() function weren't very helpful to me. Maybe it's my limitation...

Anyway, I'm still curious how to close figure from my initial message, so that memory won't leak. I welcome your replies
