Do we really need a parallel list here?
forv i = 1/10 {
tmap choro var`i', id(county) title("Disease `i'")
graph export "`i++'.png", replace
}
Or, how do you like:
local i 1
foreach var of varlist firstvar-lastvar {
tmap choro `var', id(county) title("`:var label `var''")
graph export "`i++'.png", replace
}
