not sure I understood you correctly, but does the following come close?
sysuse auto
generate interesting=(price>10000)
scatter price weight [aw=rep78] if foreign==1 & interesting==0,
msymbol(Oh) || scatter price weight [aw=rep78] if foreign==0 &
interesting==0, msymbol(Oh) || scatter price weight [aw=rep78] if
interesting==1, msymbol(O)
