I'm not sure where to find a good explanation of that, but let me give you
some hints. It is intended to use show only once per program. Namely 'show'
should be the last line in your script. If you want interactive plotting you
may consider interactive mode (pyplot.ion-ioff) like in the example below.
Furthermore for dynamic plotting all animation demos might be useful.
Maybe you want to have also a look at
best regards Matthias
from pylab import *
t = linspace(0.0, pi, 100)
x = cos(t)
y = sin(t)
ion() # turn on interactive mode
subplot(111, autoscale_on=False, xlim=(-1.2, 1.2), ylim=(-.2, 1.2))
point = plot([x], [y], marker='o', mfc='r', ms=3)
for j in arange(len(t)):
# reset x/y-data of point
setp(point, data=(x[j], y[j]))
draw() # redraw current figure
ioff() # turn off interactive mode

I still haven't figured out how to fix it, so any feedback would be
