True, although if there's only one axes, it's obvious ;-)
(and if there's more than one, it should take an axes as a keyword
parameter)

Who knows, maybe someone would want that? The joy of building generic
tools ;-)

Yes, you see, it just feels to me like figlegend should have this code
in it as it's likely to be duplicated every time I need to call figlegend.
Why not just?
figlegend(axes=ax1,'upper right')

Yes, I'm just making do with this for now, but it would be really nice
if MPL supported legends outsite the axes properly.
It would also be good if you didn't have to manually fiddle with
subplot_adjust because you rotated the labels for the x-axis through 90
degrees :-(

'badly' I think is the best summary of the interaction ;-)

Yeah :-/ This is where I am... If anyone has any magic code or
suggestions, I'd love to hear 'em ;-)
