-devnplot- (SSC) gets you some if not all of the way.

-graph dot- may be the most neglected graph command in official Stata.
Note that it has a -vertical- option (undocumented though that is, I
believe).

That said, it is

1. Very easy to run out of real estate here. Identifiers on three
different levels?

2. Often better to plot identifiers so that they read horizontally.
What may bite here are your patient ids. If they are at all long, they
may not fit at all on the x axis.

Consider

 sysuse auto, clear

 graph dot (asis) mpg if foreign, over(make) over(rep78) nofill

graph dot (asis) mpg if foreign, over(make, label(ang(v))) over(rep78)
nofill vertical

I would like to show this in a scatter plot with scores on the y-axis and patient id on the x-axis, which is easy to do. However, I want to show that patients are nested within therapists. One potential approach is to sort the x-axis of the scatter plot by providers and patients within providers and add a second x-label under patient_id to represent therapists (to show nesting). I am wondering if anyone can suggest how to do this in Stata or use a different approach to represent the heterogeneity in a 3-level data structure (occasions nested in patients, and patients nested in providers).
