Hi Scott,

You can use the .ortho_ray or .ray objects to do this sort of query, and then query based on the positions from the resultant object. Because you might have AMR data, there's also a normalized "t" and "dt" coordinate system that shows order-of-traversal, too.

Hi Yt users,

I'm looking for something like the projection and slice plot, but as a 1D lineout rather than 2D projection or slice. In other words, is there a simple way to make a line plot of "x" vs. "density" at y = z = 0, for example? I unsuccessfully tried modifying the 1D profile examples, which talk about sub-regions (e.g. spheres) and plotting two data variables against one another (e.g. "dens" and "temp"). Has anyone else run into this issue? I am guessing I am just missing something simple. Thanks!

Scott
