[yt-users] Plot collections on non-square slices

Hi YT Users, I have a computational domain that is not cubical, and I want to plot a slice through it that is rectangular rather than square. I can make a slice with PlotCollection, but when I write the image to a file using save, I find that it has been padded with whitesapce on the left and right to make it square. I would like the image to have the same aspect ratio as the data, not be white-padded. Is there a way to do this with PlotCollection, or should I just give up and use FixedResolutionBuffer to extract the data and construct the image myself? Thanks. -- Mark Krumholz krumholz@ucolick.org
