Hi,

First ;-) I don't know Tk or plot, but from looking at your code I see you want 
to plot
a line a minute long, after that, all dots are drawn to the screen. You call

>                self.graph.addSet(x,y)

My guess is that you have to explicitly draw to the screen using same call from
graph or self? whatever Tkinter wants. Search the tkinter/tk docs for 'draw'
calls.
