Re: [Visualpython-users] clear the graph object

[Bruce S. <Bru...@nc...>]

That should free up memory eventually, when Python does garbage=20
collection. Python keeps a reference count on all objects (and Visual=20
adds another one if the object is visible, because the human user=20
constitutes another reference to the object, which is why you have to=20
make the object invisible before deleting it). When the reference count=20
goes to zero, Python can delete the data from memory., At least that's=20
the way it's SUPPOSED to work.
