[yt-users] ortho_ray question

[Michael Zingale]

Here's the doc I think refers to this, which says it's an order list:

http://yt-project.org/docs/dev-3.0/reference/api/generated/yt.data_objects.selection_data_containers.YTOrthoRayBase.html#yt.data_objects.selection_data_containers.YTOrthoRayBase

I found this functionality via google.  But I don't have a t field here.  I
can sort based on "x" though.
