I have to make a stacked area chart in Stata with a vertical line at a certain date. However, I haven't been able to make the line be over the shaded area of the chart. Does anyone know if its even possible?
Here's the code and the chart.

Code:
insheet using "https://covid.ourworldindata.org/data/ecdc/full_data.csv", clear
keep if location == "Venezuela" | location == "Colombia"
keep date location new_cases
reshape wide new_cases, i(date) j(location) string
drop if new_casesVenezuela==.
gen year = substr(date,1,4)
gen month = substr(date,6,2)
gen day = substr(date,9,2)
destring year month day, replace
drop date
gen date = mdy(month,day,year)
format date %tdDD-Mon-yyyy
drop year month day
gen date2 = date
gen total = new_casesColombia + new_casesVenezuela
gen porc_col = new_casesColombia / total
gen porc_ven = new_casesVenezuela / total
gen zero = 0
gen uno = 1
gen acum1 = porc_col + porc_ven
twoway rarea zero uno date ///
|| rarea zero porc_col date ///
|| rarea porc_col acum1 date, legend(order(3 "Venezuela" 2 "Colombia") col(1) pos(6)) xtitle("") xline(22100)
graph export "test.png", as(png) replace
