hi,

I tried to plot in realtime:

from pylab import *
import time

ion()

x=arange(0,2*pi,.01)
line,=plot(x,sin(x))
for i in arange(1,20):
    line.set_ydata(sin(x+i/10.0))
    draw()


but nothing happens when the script runs. I just see the last plot after the 
script has finished. Only a grey empty window during processing.

I tried to start it in ipython (stated with --pylab) as well as with python and 
pythonw on OS X Tiger.
I use Pyhton 2.4
matplotlib-0.87.7
wxPython 2.8.0

any hints for me?

thanks Jan
