try the function plot:

graph twoway function (1+1/x)^x, yline(`=exp(1)') range(0 10) ylabel(1 2
`=exp(1)' "e" 3)

you don't have to create the data, and you easily combine it with other
plots.

Something like this?
Phil

clear
set obs 300
gen n=_n
gen y=(1+1/n)^n
line y n, yline(`=exp(1)', lstyle(refline)) ///
	ytitle("(1+1/n){sup:n}", orient(horiz)) ///
	ylab(`=exp(1)' "e", add angle(horiz))
