[Matplotlib-users] how to close (complitly destroy) pylab figure?

[dmitrey <dmi...@sc...>]

Hi all,
how to close (complitly destroy) pylab figure?

The feature is highly required for my module "openopt".

I expected something like this will work but it doesn't

from pylab import *
ion()
plot([1, 2, 3, 4], [1, 2, 3, 4])
draw()
# optional: ioff(); doesn't help as well
close('all')

Thank you in advance,
Dmitrey.
