Re: [Matplotlib-users] show()

[Jean-Michel P. <jea...@ir...>]

Ok. Now suppose you write an application that runs a set of algorithms 
not known in advance. These algorithms may or may not create figures 
depending on what they perform; they may also encounter difficulties 
(e.g. not enough input data) so that none of them is finally able to 
create a figure. As this is always better to dissociate code pieces the 
more as possible, I'd prefer not to use a global variable to trace 
figure creation. So is there a way to know that no figure was created?

Regards.
