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 !

Regards,

David
