[yt-users] stitching data sets together

Hi Everyone, I have data for a simulation in spherical coordinates that I wish to input into yt and visualize using the generic reader tools. However, the simulation is broken up into six volumes, each of which is a solid angle that makes up part of a sphere. Unfortunately, stitching together the arrays of data produces a lot of redundancies, there's no easy way to include all of it in a single array without including the same data points several times. So what I'd like is a way to feed in each solid angle as an individual data set, but visualize all six datasets on a single plot. Is this possible? Thanks in advance for your help! Best, Jonah MIller
