Has label grouping made it into the matplotlib features yet?

I’ve run into this SO question a year or so ago

http://stackoverflow.com/questions/19184484/how-to-add-group-labels-for-bar-charts-in-matplotlib

and have recently run into several questions similar to it again. I’m not aware that this is available in any form or fashion from the matplotlib main features unless users reuse his code or make their own.

My question is: does this feature exist somewhere in mpl and I’m just unaware of it? If there’s not is it in the planned features list?

I think it’s a worthwhile feature to have and from what I see there’s a lot of people asking similar questions already.

Thanks,

Dino
