Thank you, Scott and Nick. Thanks to your help I can now draw a graph
with proper labels.
#delimit ;
sysuse uslifeexp, clear;
keep if year>1918 & year<1925;
forval i = 1/6 {;
local le: di %4.1f `=le[`i']';
local tbox "`tbox' text(`=le[`i']' `=year[`i']+0.05'
"`le'", box bc(white) place(e) size(small))";
local le_male: di %4.1f `=le_male[`i']';
local mbox "`mbox' text(`=le_male[`i']-0.2' `=year[`i']'
"`le_male'", box bc(white) place(s) size(small))";
local le_female: di %4.1f `=le_female[`i']';
local fbox "`fbox' text(`=le_female[`i']+0.2' `=year[`i']'
"`le_female'", box bc(white) place(n) size(small))";
};
scatter le year, connect(l) `tbox' ||
scatter le_male year, connect(l) `mbox' ||
scatter le_female year, connect(l) `fbox'
xscale(r(1918.8 1924.3)) yscale(r(53 62.5));
