[yt-users] Profile of a projected quantity?

Hi all, Is there a way for me to find a profile using a projection as a data source? In particular, I'd like to find a radial profile of a surface density in a disk galaxy simulation. I think I could do this by histogramming a fixed resolution buffer created by a projection data source but is that the only way to do it? I'd prefer for my data pipeline to look identical for computing profiles and in all other cases I'm using a Profile1D object to find things like the cumulative mass or the average density as a function of radius. Thanks for your help with this! -Nathan
