graphing/plotting with python and interface builder

Thanks for the reply.

I have wxPython installed and have used it.  with wx I have just been  
using the wx.lib.plot module and the graphing is fine (although in  
other posts I note some focus issues).

I have been looking at moving to using interface builder 3.0 and  
building Cocoa apps because for a bigger project it might be faster  
and better code.

I only want to make plots that show data... but I need to refresh the  
plot at every step.  with wx.lib.plot, i just draw it again  
(performance is not too big of an issue).  No user interaction is  
needed.

I will check out Chaco.  Like I said, I know how to use wx.lib.plot,  
so if there is a way that I can use the graphs created there that  
would be great... although I suspect that wx.lib.plot requires a frame  
as a parent, which I would not want to use since .nib files (from  
interface builder) would handle the gui side with PyObjC (a language  
which I don't know).

Thanks

Jake
