This is necessary given that the syntax of -legend- is designed to handle much more complex graphs. There are two ways of doing what you want: 1) Say to Stata that the first line represents drug 1 and and second line drug 3: *----------- begin example --------------- sysuse cancer.dta, clear stset studytime, failure(died) drop if drug == 2 sts graph, by(drug) atrisk /// legend(label(1 "drug 1") /// label(2 "drug 3")) *------------ end example ---------------- (For more on how to use examples I sent to the Statalist, see http://home.fsw.vu.nl/m.buis/stata/exampleFAQ.html ) 2) Assign labels to the values of the variable drug: *----------- begin example ----------- sysuse cancer.dta, clear stset studytime, failure(died) drop if drug == 2 label define drug 1 "drug 1" 2 "drug 2" 3 "drug 3" label value drug drug sts graph, by(drug) atrisk *------------ end example ------------ (For more on how to use examples I sent to the Statalist, see http://home.fsw.vu.nl/m.buis/stata/exampleFAQ.html ) Hope this helps, Maarten ----------------------------------------- Maarten L.
