Why do you think you couldn't do it with matplotlib?
It seems a fairly basic request.
I have no experience with either package but matplotlib is the 
first place I'd look for this.

There is also gnuplot which I've used outside Pytthon, but it 
could do this too I'm sure.

OTOH It would be fairly easy to roll your own in a vanilla 
GUI Canvas widget. Its only a few stratight lines and text after all.
Or even to use a scroll bar or progress bar widget to indicate 
the result.
