the elements you need to solve your problem. Here is an example:

*-------------- begin example -----------------------
sysuse auto, clear

parmby "mean trunk mpg turn", by(foreign) norestore
gen x = _n

scatter estimate x ||                 /*
*/ rcap min95 max95 x,                /*
*/ xlab(1 "trunk"                     /*
*/ 2 `""mpg" "Domestic""'        /*
*/ 3 "turn"                      /*
*/ 4 "trunk"                     /*
*/ 5 `""mpg" "Foreign""'         /*
*/ 6 "turn")                     /*
*/ legend(order(1 "mean" 2 "95% CI")) /*
*/ xtitle("")
*------------------ end example -------------------------
