I'm having problems figuring out where to bind any callbacks to widgets/objects so that I can redraw/adjust my lines/rectangles/text.

Look how I did it in Tk Realtime data aquisition

P.S. In Tk, you can always run little timers, that will auto refresh the canvas at a specified interval, like every 10 ms. Then all you need to do, is receive your data into an array, which the update sub would read from. 10 ms is very fast for human eyes to perceive, so it looks smooth.

I'm not really a human, but I play one on earth.
