Does this do it?
// ------------------------------------------------------------------------------
sysuse auto, clear
tostring rep78, replace
local scatter ""
levels rep78, local(rep78)
foreach r of local rep78 {
local scatter `"`scatter' (scatter mpg weight if rep78==`"`r'"', msize(large))"'
}
di `"`scatter'"'
// ------------------------------------------------------------------------------
