As you say, this is a standard kind of graph. I would write a do-file
separating out the data management from the graphs. I've found
-statsby- very useful for confidence intervals and there was an essay
to that effect in

SJ-10-1 gr0045  . . . . . . . . . . . . . Speaking Stata: The statsby strategy
        . . . . . . . . . . . . . . . . . . . . . . . . . . . . . .  N. J. Cox
        Q1/10   SJ 10(1):143--151                                (no commands)
        demonstrates the use of statsby to prepare a reduced
        dataset for subsequent graphing

I am not clear that you need think about this as requiring an ado-file.
