You are probably looking for -twoway rcap-, see -help twoway rcap- and
the example below:
*---------------- begin example ------------
sysuse auto, clear
collapse (mean) mean=mpg /*
*/ (sd) sd=mpg /*
*/ (count) N=mpg, by(rep78)
gen df = N-1
gen lb = mean - invttail(df,.025)*sd
gen ub = mean + invttail(df,.025)*sd
twoway scatter mean rep78 || /*
*/ rcap lb ub rep78
*------------- end example -------------------
(For more on how to use examples I sent to the Statalist, see
http://home.fsw.vu.nl/m.buis/stata/exampleFAQ.html )
Hope this helps,
