Hi,
I have a simple script that plots x,y vals in an animation called anim.py
data = read('data.dat')
for i in range(10):
plot(data[:,0], data[:,1])
I am using ipython -pylab but when I do run anim.py it doesn't show
anything until I say show(). On the other hand, if I do one of these
plotting commands from the ipython terminal it shows up right away.
It seems that everything works fine once one thing has been plotted
from the ipython command line. Is there any way to fix this so that
it plots right away as expected?
Thanks,
Jon.
Hi Jon,
I can reproduce you observation using the following program
-------------------------------------------------
from pylab import plot, arange, ion
##ion()
plot(arange(10), arange(10))
--------------------------------------------------
uncommenting the second line resolves the problem at least for me. That is an
additional switch to interactive mode is needed, but I can't explain why.
My matplotlib is:
In [1]:matplotlib.__version__
Out[1]: '0.98.6svn'
Can you reproduce this behaviour and can anybody else explain that?
regards Matthias
