Re: Centering Text with axes_divider

Greetings,

Let me begin by saying that I've fallen in love with ImageGrid. I love the control it gives me in setting up plots, and I really like the control it offers for setting up a colorbar. Unfortunately, like all relationships, ImageGrid and I have hit a rough patch.

I like to manually place titles and other boxes of texts on plots that I make using ImageGrid. However, to center things I have to know what the axes bounds are so I can do the centering calculations. Unfortunately, when using ImageGrid, or axes_divider, I have yet to find a way to get the axes bounds that are actually used to do the plotting. When I try to use 

ax.get_position().bounds

I get the pre-adjusted bounds, even if I use plt.draw() before requesting the axes_positions. This means the only way I can center the text is by guessing what the final axes bounds will be.  Is there any way of getting the final bounds? It appears anchored text is able to do it, but I haven't been able to...

Here's a self-contained example script that demonstrates the problem.  I don't use ImageGrid, instead using axes_divider, however this is the same problem that AxesGrid has. (I'm guessing this is because ImageGrid ultimately does what I did here behind the scenes.)

Thanks for any help!
