Is there any efficient way of illustrating these following policies in a stacked bar graph like the provided code I'm attaching here? Any advice? I'm getting invalid syntax [ r (198) ] for using this attached code for these policies.

I want to show over the years the total number of states took these policies in. a stacked bar graph.

Code:
gen min_wage=0

replace min_wage = 1 if year>=2015  & (statefip==2 /*alaska*/)
replace min_wage = 1 if year>=2015  & (statefip==5 /*Arkansas*/)
replace min_wage = 1 if year>=2013  & (statefip==4 /*Arizona*/)
replace min_wage = 1 if year>=2015  & (statefip==6 /*California*/)
replace min_wage = 1 if year>=2015  & (statefip==9 /*Connecticut*/)
replace min_wage = 1 if year==2015  & (statefip==8 /*Colorado*/)
replace min_wage = 1 if year>=2014  & (statefip==11 /*Dis.of Col*/)

gen min_wagead=0

replace min_wagead = 1 if year>=2018  & (statefip==32)
replace min_wagead = 1 if year>=2017  & (statefip==35)
replace min_wagead = 1 if year>=2017  & (statefip==34 )
replace min_wagead = 1 if year>=2015  & (statefip==36 )
replace min_wagead = 1 if year>=2018  & (statefip==39 )
replace min_wagead = 1 if year==2019  & (statefip==48)
replace min_wagead = 1 if year>=2019  & (statefip==51)
This is the command I'm using for illustration of a stacked bar graph for these policies :

Code:
graph bar statefip if min_wage==`1' & min_wagead==`1', over(year) bar(1, color(usaid_red) lcolor(black)) bar(2, color(usaid_darkgray) lcolor(black)) ///
                    blabel(total, position(inside) format(%2.0f) color(white) /*size(5)*/) stack ///
                    title("# of states using minimum wage") ///
                    note("Source: Minimum wage) ///
                    legend(label(1 "# Minimum wage initial") label(2 "# Minimum wage later")) graphregion(color(white))
