[Matplotlib-users] Interactive use of matplotlib in ipython

[Wolfgang K. <wke...@go...>]

Hello,

I would like to build a bit of an interactive fitter with matplotlib and ipython (in pylab environment). I would like to have a a function, which takes x and y as input, then plots these and fits a line to it (just numpy polyfit). if I click a point it will be removed from the fit pool and the line will be refitted (optionally after pressing 'f'). when I'm done I can press 'q' or close the window and the function will come to an end and spit out the fitting parameter. 
I tried this a year or two ago and I had terrible problems with getting stopping the event loop and waiting for the interactive part to finish and then finish the function. I'm running os 10.6 and use the wx backend (or mac os x, if that's easier). Can you point me to an example or give me a crude overview of how to do that in the right way. Is that understandable?

Cheers
    Wolfgang
