Anyone able to “see” an animation using WXAgg 2.6 or otherwise on OS X 10.4 python 2.5 mpl 0.90.0
I can save figures and make a movie but nothing shows in the figure window until the animation is over.
even the example anim.py has the same behavior.
I have only been able to get it to work with tkAgg but that is seg faulting now.

Please post a as-small-as-you-can-make-it sample, and I'll give it test here.

I'm not too surprised. OS-X double buffers behind the scenes, and I think it waits until it thinks there is good reason to before it updates the screen. You need to force it in your code quite explicitly in a way you don't on other platforms. You might try adding a Refresh() and Update() call to the relevant wx.Window. Or maybe you need to do a wx.App.Yield()

oops, I guess I can try that! Maybe I can get to it later today -- no time now!

I am not sure how I do that from matplotlib running in ipython
How do you get a handle to wx.Window and wx.App.Yield from MPL?
I do animations by calling MPL functions inside ipython --pylab.
Do you approach animations in a completely different way?
