Hi, I am trying to create a series of Kaplan-Meier survival curves based on a series of categorical variables. Each variable's values have labels assigned to them. Accordingly, when I run the code below

Code:
local rvar olc omc ouc dlc dmc duc
foreach i of local rvar {
    sts graph, by(`i')
}
I obtain a graph like this
Array




How could I go about removing the "olc = " in the legend? I know that I can use legend(lab(1 "Group A") lab(2 "Group B") lab(3 "Group C")) but each of the variables in my loop do not have the same value labels. Accordingly that solution would not work for me. Is there a better way to get what I want rather than run separate lines of code each of the graphs?
