That is what the new -marginsplot- command is good at:

*-------------- begin example ----------------
sysuse auto, clear
reg mpg c.weight##c.weight foreign i.rep, vce(boot)
qui margins , at(weight  = (1720(20)4840) ///
                 foreign = 0              ///
                 rep78   = 3 )
marginsplot, recast(line) recastci(rarea) ///
*----------- end example ------------------
(For more on examples I sent to the Statalist see: )

Hope this helps,
