[Paraview] pvpython and matplotlib

[Aurélien Marsan]

Good morning Adriano,

All is working fine for me.
But I remember that pyplot.show() didn't work from the paraview python
sheel with previous release.
It looks like you have the 2.4 verions of Python. Which Paraview version do
you use ?

Regards,

Aurelien
