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.
