The following steps modify the line thickness for the step functions in the survival plot:

%ProvideSurvivalMacros

%let StepOpts = lineattrs=(thickness=2.5);

%CompileSurvivalTemplates

proc lifetest data=sashelp.BMT plots=survival(cb=hw test);
   time T * Status(0);
   strata Group;
run;

The results are displayed in Figure 23.20.

By default, the StepOpts macro variable is null.
