is it possible to have an interactive session through pydev for using matplotlib? The problem is that I cannot get shell access to drive the charts as the interpretor halts after the show() command. I would like to have an interactive session through pydev.
Interactive sessions are well described by the matplotlib manual here: http://matplotlib.sourceforge.net/users/shell.html
However, no example is provided for doing this is eclipse.
I've not used pydev much, but IIRC you can change which interactive interpreter you use. If that's possible, install ipython and use it in pylab mode (ipython --pylab from the command line)
Turns out you can't change the interpreter. You can run interpreter commands so maybe it's possible to run an ipython shell that way, but it would be easier to just launch ipython --pylab from a terminal and run it along side your eclipse session.
HTH
Or just launch ipython from a terminal and run it along side your eclipse session.
You can also use a plugin WickedShell.
I guess that the problem is that the toolkit you use needs to run its event loop, and it is probably not compatible with running under Eclipse. You could try using the Agg backend, saving your figures and opening them in a separate viewer.
There's something called ezplot for plotting in another process via RPC: That would solve the event-loop problem nicely, but it seems that it is not up to date.
