Color of Line, Lifetest Plot (Using Warren K's macros)

I found this instruction in Warren Kuhfeld's documentation for controlling the color of the LIFETEST plot line:

%let GraphOpts = DataContrastColors=(red green blue)

DataColors = (red green blue);

However, I find that this only works when a STRATA statement is used. I'm plotting a single group, and don't want a STRATA (because I don't want a legend or the strata title in the plot). But the line comes out gray without the STRATA.

It's not the end of the world, but is there a way to have a non-gray line without STRATA label in the to

Where do you use this macro variable?

Show the code please.

Hi @daveconifer1,

The macro code (see macro SingleStratum) suggests that for your purpose macro variable StepOpts is relevant. Modifying the example Changing the Line Thickness to

%ProvideSurvivalMacros

%let StepOpts = lineattrs=(color=red);

%CompileSurvivalTemplates

proc lifetest data=sashelp.BMT plots=survival(cb=hw test);
   where Group='ALL';
   time T * Status(0);
   /* STRATA statement removed */
run;

yields a red Kaplan-Meier curve (for group 'ALL').
