[yt-users] title of PlotCollection

[Sam Skillman]

Hi Penfei,

It seems there might be a bug in the title callback.  In the meantime while
we fix the bug (I will file an issue to be resolved), you may want to use
the text callback:

If you want some text over on the right side near the colorbar, you should
have decent luck with:

p.modify['text']((1.15,0.9), 'z=%.2f'%z)

or if you want to place it in the middle, which you'd probably want the
color to be white, you could do something like:

p.modify['text']((0.5,0.9), 'z=%.2f'%0.1, text_args={'color':'w'})

The numbers in the () denote the fractional position in x,y in the image
part of the plot.  In both of those examples, I'm assuming you've defined z
somewhere, otherwise is will still fail.

Best,
Sam
