So each row corresponds to the density value sampled over a 1x1 (in code units) region of your simulation, since you specified that you wanted a 10x10 image.You might find the OffAxisProjectionPlot object to be a bit nicer to work with to make plots:

You also don't need to create a ProjectionPlot to do this, you can instead manually create a FixedResolutionBuffer object. See the following doc pages:Hope that helps,NathanOn Sun, Jan 21, 2018 at 12:47 AM Julia Rakas <jrakas@umich.edu> wrote:Hello,
When I do yt.off_axis_projection(…) I get an array as an output. My question is how I can get an output array for regular projection plots? And does the output array correspond to the actual image that it otherwise would have plotted?
Thanks,
Julie
