Wow, impressive ! Thx a lot

Yep indeed, that's pretty much what I was considering. And parsing the
MyFigure arguments through keywords seems the easiest, I'll keep that in mind
(I used optional arguments *args, as they're not used in Figure, but that's
trickier to keep track of).
Now, till we (you ;)) are it, what about updating Figure.add_subplot() to call
user-defined subplots ? I wrote something along the lines below for my own
needs, but that might be a useful addition...
Initial add_subplot
add_subplot(self, *args, **kwargs):
...
if isinstance(args[0], Subplot) or isinstance(args, PolarSubplot):
a = args[0]
a.set_figure(self)
else:
ispolar = popd(kwargs, 'polar', False)
if ispolar:
a = PolarSubplot(self, *args, **kwargs)
else:
a = Subplot(self, *args, **kwargs)
...
Modified add_subplot
add_generic_subplot(figure, subplotclass, *args, **kwargs):
...
if isinstance(args[0], Subplot):
a = args[0]
a.set_figure(self)
else:
a = subplotclass(self, *args, **kwargs)
...
That way, if you need a PolarSubplot, you can still get it. Well, we'd have to
make PolarSubplot a subclass of Subplot instead of Subplotbase, but that
should be easy to implmnt.
