[yt-users] Lineout plot fo 3D dataset

[Nathan Goldbaum]

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:
