Re: [Matplotlib-users] Annotate not Drawing Properly in a Gridspec - Version 1.4.3

[Sean L. <ody...@gm...>]

Sterling,

Thanks for the pointer. I've already used a workaround where I used "data" coordinates and put it at:
0.9 * (xmax - xmin) + xmin, and similar for y.

I'm really only reporting this so that it can be fixed if there is someone who does need to annotate something in a grid.
