There have been several threads on Statalist on related
questions since the release of Stata 8, ranging from whether
this is a good idea to how you might do it. Recipes for "error
bar on measurement bar" plots (or what Paul Seed calls
detonator plots) appear popular with some groups of biological
scientists, and perhaps others, unpopular with those who think that
the medium muddies the message.
You should search the archives to see more.
A partial summary on how it might be done:
-graph bar-, -graph hbar- and -graph dot- don't lend themselves
to added extras.
-dotplot- has its own idea of showing mean +/- s.d.
-serrbar- is always there.
There is more scope for doing what I think
you want by superimposing a -twoway rcap- on
a -twoway bar-. Building on a suggestion by
Stephen McKay, there is some code at

Roger Newson has his own way of doing it on -eclplot-.
