Python widget for real time plotting
Tkinter, which is part of python, comes with a canvas widget that can be used for some simple plotting. It can draw lines and curves, and one datapoint every couple of seconds is very easy for it to handle.
Is there a minimalistic python module out there that I can use to plot real time data that comes in  every 2-3 seconds?
I've tried matplotlib but I'm having a couple errors trying to get it to run so I'm not looking for something as robust and with many features.
