Event_plot margin issue

[Laurence Jones]

Hi, I am trying to combine two graphs created using `event_plot`:

// regression 1
estat event, window(-4 4) estore(cs)
event_plot cs, default_look graph_opt(xtitle("Periods since the event") ytitle("ATT") ///
    title("Var1") xlabel(-4(2)4)  legend(off)) stub_lag(Tp#) stub_lead(Tm#)  ciplottype(rcap)  plottype(scatter)
graph save ga, replace

    
// regression 2
estat event, window(-4 4) estore(cs)
event_plot cs, default_look graph_opt(xtitle("Periods since the event") ytitle("ATT") ///
    title("Var2") xlabel(-4(2)4)  legend(off)) stub_lag(Tp#) stub_lead(Tm#)  ciplottype(rcap)  plottype(scatter)
graph save gb, replace

gr combine ga.gph gb.gph , col(1) xcommon ysize(7) commonscheme

The result however, has different margins on the left, I would like the plot margins to be aligned, is this possible to force?

Not a fix, but a workaround is to use `coefplot` instead:

estimates store cs
coefplot ///
(cs, keep(Tm4 Tm2) mcolor(maroon) ciopts(color(maroon) recast(rcap))) ///
(cs, keep(Tp0 Tp2 Tp4) mcolor(navy) ciopts(color(navy) recast(rcap))) ///
, vert ytitle(ATT) yline(0, lcolor(gray)) xline(2.75, lpattern(dash) lcolor(gray)) legend(off) xlabel(1 "-4" 2 "-2" 3 "0" 4 "2" 5 "4") xtitle(Periods since event)
