Yes your wright the script have to work in non interactive mode. (I was jus=
t
trying to give an explanation to Emmanuel problem).
The following script should work (but it crashes like Emmanuel reported):
#!/usr/bin/python
import matplotlib
import pylab
#Turn off interactive mode
matplotlib.interactive(False)
#plot figure 1
pylab.figure()
pylab.plot([1,2,3],[1,2,3])
pylab.savefig("test_pylab1.png")
pylab.close()
#plot figure 2
pylab.figure()
pylab.plot([1,2,3],[1,2,3])
pylab.savefig("test_pylab2.png")
pylab.close()
Second figure cannot be created due to the crash.
We need the help of matplotlib Gurus !

David

Hi,
What one can do is :
f =3D figure(1)
... some figure
f.clear()
f =3D figure(1)
... another figure
f.clear()
However, it is only a work around, not an actual solution...
Cheers,
David

This is a bug and I fixed it in CVS (Steve take a look and see if you
agree with the show._mainloop approach) but basically you don't want
to use matplotlib this way.
If you do not want the figure to pop-up, that is you only want to
create a PNG and move on, just use the Agg backend rather than GTK*.
Eg
python myscript.py -dAgg
The problem you experienced arose because you closed all the figures
before you called show in non-interactive mode. For a GUI this makes
no sense, because you are telling the GUI to close all the windows
before it shows any of them.
I fixed the GTK backend to not try and quit gtk before starting it :-)
In summary, I recommend:
* in non-interactive mode with a GUI backend, always end your script
with show. This starts the GUI mainloop. Do not close all your
figures before you call show.
* if you don't want an image to pop up, use non-interactive mode,
and a non-GUI backend, and show is not required but it doesn't
hurt either.

Hi David,
I was in non interactive mode. But I finally solved the problem by replacin=
g=20
the GTKAgg backend by the TkAgg one. I don't understand why the GTKAgg does=
=20
not work, but well... if the TkAgg does...
