I apologize if this has been covered before, but I can't find it in web or ticket searches...
How do I plot a Trace or Stream without blocking the ipython terminal? matplotlib.pyplot.ion() does not do it.
for me (Linux/Debian Lenny) it works using `ipython -pylab`. I think it
might depend on the operating system you are working on, though.
You can also try the new IPython 0.11 which has many new features in
that direction
(http://ipython.org/ipython-doc/stable/whatsnew/version0.11.html) like
the new inline Qt console and an improved debugger. I haven't tried it
myself yet but I've heard lots of positive feedback.
