ipython and figs with mplot3d

#1

hi
i've just upgraded to 0.99, and trying out mplot3d for the first time -
wondering if a few things are standard behaviour or not. any example i
choose from the standard bunch will work fine with "%run ***" in
ipython, but once the figure is drawn and closed, i no longer have the
ability to plt.show().

also, if i don't %run anything, but try and work my way through
interactively by ipython (with "-pylab") commands, no axes can be
generated (Axes3D imported) with "ax=Axes3D(fig)" - just nothing
happens in the figure brought up previously by "fig=plt.figure()".

if i start ipython without "-pylab", it works - sort of. running
step-wise through the example will work fine, though i lose the ipython
command line while the figure is open. when it's closed, though, i
can't get another figure to display at all - sort of like the first
problem i mentioned not being able to plt.show() again in the same
interactive session.

so, is this normal?

thanks

Hi,

This sounds like expected behavior to me; plot() is only supposed to
be called once to draw all the figures that have been generated up to
that point.

also, if i don't %run anything, but try and work my way through
interactively by ipython (with "-pylab") commands, no axes can be
generated (Axes3D imported) with "ax=Axes3D(fig)" - just nothing
happens in the figure brought up previously by "fig=plt.figure()".

Strange, but I indeed see the same behavior here; I'll look into it!

if i start ipython without "-pylab", it works - sort of. running
step-wise through the example will work fine, though i lose the ipython
command line while the figure is open. when it's closed, though, i
can't get another figure to display at all - sort of like the first

interactive session.

Again, this is expected behavior.

so, is this normal?

Concluding: partly yes, partly no, thanks for reporting!

Reinier
