issues with Stsgraph legends with confidence interval option

[Sakshi Rajatbhai Tewari]

Hello all, previously I never have issues when I generate sts graph with "ci" option, it automatically knows to assign different colors to the different strata and create line legends for their respective confidence intervals. However when I tried to generate today using this code:

sts graph, by(stratacig)  ytitle("Proportion of cancer cases") legend(order(1 "Never smoker" 2 "Ever smoker, <20 packyrs" 3 "Ever smoker, 20+ packyrs")) xtitle("Followup time (years)") note("P=0.005") title("Progression free survival") ci

I saw this:

Your manual labeling does not necessarily correspond to the order of plots. With 3 pairs of CIs and lines, perhaps you need:

legend(order(1 "Never smoker" 2 "" 3 "Ever smoker, <20 packyrs" 4 "" 5 "Ever smoker, 20+ packyrs" 6 "") row(3))

A data example is needed if the above is not helpful.
