John,
A similar question came up last month. Gerald Wright ([email protected])
came up with this example to show how it may be done:
preserve
sysuse gnp96,clear
sum gnp
local max=`r(max)'
gen c=`max' if date>q(1992q1)&date<q(2001q1)
lab var c "Clinton Years"
twoway (area c date, bcolor(gs15)) (line gnp date, clpattern(solid))
restore
Hope this helps,
Scott
