Using the following command and using the data, you can use an event study graph for only one set of regressions, but I want to create the same graph for multiple regressions. So, I can show how for different groups the treatment is behaving differently ( like for low-education and high education people the treatment will have a different impact). With the following code, there will be one set of regression for either: low-education or high education. But, I want to edit the following code so that I can show in the same graph how both groups are behaving since the effect of treatment and before treatment. Right now my graph looks like this ( the attached image )

BUT I WANT TO EDIT MY CURRENT CODE SO THAT FOR MULTIPLE GROUPS I CAN USE THE SAME REGRESSION TO PRODUCE THE GRAPH I'M GOING TO ATTACH IN THE COMMENT.

Code:
*** ssc install eventdd

use "http://www.damianclarke.net/stata/bacon_example.dta", clear
gen timeToTreat = year - _nfd
eventdd asmrs pcinc asmrh cases i.year i.stfips, timevar(timeToTreat) method(ols, cluster(stfips))

*Then storing the estimates

estimates store leads_lags

#delimit ;

coefplot leads_lags, keep(lead5 lead4 lead3 lead2 lead1 lag_0 lag1 lag2 lag3 lag4 lag5plus)
