Ahh Thanks Nathan, 

I missed it in yt-3.0 because it is called "annotate_grids()" and it is associated with the GridBoundaryCallback class.  Also, it is totally broken in yt-3.0 so I will probably be fixing it up. 

Be Well

Hi Anthony,

Yes there is, annotate_grid (see the grid callback in plot_modifications.py.).
