I am attempting to combine 2 graphs together.

Here's my code:


eststo: reg varlogwageinc i.agegrp9 i.year [aweight=wgt], robust
coefplot (time_effect, recast(connected) ciopts(recast(rline) lpattern(dash)) ) ///
, vertical yline(0) keep(*.agegrp9) nooffsets ///
xtitle("Age") title("Variance of Log Wages")

eststo: reg varlogwageinc i.agegrp9 i.cohort [aweight=wgt], robust
coefplot (cohort_effect, recast(connected) ciopts(recast(rline) lpattern(dash)) ) ///
, vertical yline(0) keep(*.agegrp9) nooffsets ///
xtitle("Age") title("Variance of Log Wages")
