SGPLOT swimlane with different symbols at same timepoint

[VCM]

Asking for a co-worker (no, really I am!)  so I don't have specific code (I'm not on his project...)

He is making a swimlane plot with subject ID on the y-axis and timepoint on the x-axis.  There are only a few subjects, so the bars are "thick" to fill up some space.

On these bars he is placing 2 symbols--X and a square--representing events that are not necessarily related, using scatterplot.  However, we have subjects for whom these 2 events happened at the same timepoint:

Subject #2 shows how these symbols actually print--the two of them overlay each other.  However, the client wants it displayed like subject #1, with the symbols stacked. 

Any ideas?

Many thanks!

Try using the JITTER option on the SCATTER statement.
