Hi Scott,

You may want to try the ray data object.

Keep in mind that the ray object by default returns unordered data, so you need to sort the data first to make an ordered plot along the ray's length.

Also, keep in mind that for AMR data the ray might return variable-resolution data, so you will need to do some additional processing to generate a continuous line plot.

More info about the ray data object here:



and an example:

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!
