How to handle output window minimize/movement in interactive mode of matplotlib

I want to dynamically update the scatter plot based on the y-axis data received from a socket connection. I used python matplot lib in interactive mode to do this, but during dynamic updation if i move the window to a different location or minimize the window then the plot updation stops abruptly. Please let me know how to do this?

I have attached a sample dynamic updation code used here and the same problem appears here also, please help.

Hi

If you manage to do this, I'd be very interested! I use matplotlib to make my plots for papers, presentations etc, but also use python to control experiments, and couldn't figure out how to do this exact thing with matplotlib, although I didn't try as hard as I could yet! Still somewhere down there on my to do list!

Anyway, the way I solved it was with gnuplot, and the corresponding gnuplot module for python. I don't really know how to use gnuplot, but you don't really have to, as it's a similar kind of interface to matplotlib.

However, I have a feeling there's a python mega widget (PMW) or something similar that might be better still for this purpose. I vaguely remember seeing something about this in Langtangen's excellent Python Scripting for Computational Scientists. I'll try to remember to look it up when I get back to the office.

Ya I figured out how to do this...You need to use wxPython with matplotlib for this purpose...refer this link for more
