Differences between on-axis projections and off-axis projections
Hey everyone, Now that the righthandedness has gone into the PlotWindow objects, making slices and projections of isolated disk galaxy simulations yields the y-projection having a vertically oriented disk as seen here in an image generated by Mike Butler: http://www.ics.uzh.ch/~butler/Enzo_nofeedback_1000Myr_Sigma.png I suppose we could modify the ProjectionPlot framework to allow a keyword to specify the x-axis and y-axis vectors, but I was just trying to make equivalent projections using the OffAxisProjectionPlot object since that allows for one to explicitly specify a north_vector. Unfortunately, I'm finding some inconsistencies between the ProjectionPlot (on-axis) images and the OffAxisProjectionPlot images (specifying vectors to be on-axis). This simple script demonstrates what I'm talking about: http://paste.yt-project.org/show/5049/ Running this script yields 4 images: off_axis_proj.png - http://i.imgur.com/CKbq5iO.png on_axis_proj.png - http://i.imgur.com/2iBucuv.png off_axis_weighted_proj.png - http://i.imgur.com/RQV2REP.png on_axis_weighted_proj.png - http://i.imgur.com/CNWHyQS.png As you can see, the off_axis_proj is using significantly different limits than the on_axis_proj, which makes me think it isn't doing a true line integral, but I haven't investigated this closely. While the weighted projections are better, they still have slight differences in their limits. Is this expected and I'm just messing something up here, or is this a true bug?
