I don't know a way of doing this easily. A Stata Tip on
classifying data points on scatter plots in press in Stata Journal
5(4) 2005 offers one work-around.
graph matrix T1 T2 T3, ms(none) mlabel(MarkOut) mlabpos(0)

This is a typo in the manual. The option should be
ylabel(0(5)40, axis(1))
The typo also occurs (together with another) in the on-line help.
