Adding a vertical AND horizontal line using coefplot

[Kait Sims]

Hi statalist!

I'm using coefplot for an event study where year -1 is the reference year. I have a horizontal line at 0, but I want to add a vertical line between year -2 and year 0 (where year -1 would be). I'm plotting pretty simply using:

reg outcome $treatments, absorb(id year) 
coefplot, vertical keep($treatments) yline(0)

And this is what the resulting graph looks like:



Thanks in advance!

coefplot is from Stata Journal as you are asked to explain. You provide no data example, but I think you want

coefplot, vertical keep($treatments) yline(0) xline(2.5)

Note you can also explicitly specify the inclusion of the base level using the option

baselevels

The following link shows you how you can omit the base level marker and include a vertical line at that point.

That works perfectly Andrew! Thanks so much!
