How do I plot line graphs for multiple groups with gplot?

[dr2014]

Hi all,

I need advice on how to "plot lines for multiple groups within a sas variable". I used proc lifetest to get output dataset and used proc gplot to produce an rtf file.

proc lifetest data= abc method=KM outsurv=xyz plot=(s); time duration*censor (1,2);
strata group ; run;

The variable "group" has "6 categories" and proc gplot gives me plot points by default so I used symbol statement with i=spline option, but it gave me a line graph for only one group

Here is the code:

proc gplot data = xyz;
symbol1 i=spline;
plot survival*duration= group / vaxis=axis1 haxis=axis2 legend=legend1;;
run;

How can I get line graphs for all the categories within the group? Thanks.

I would recommend using SGPLOT instead of GPLOT to graph your data. SG procedures produce higher quality graphics, is simpler to code IMO, and have more options to customize your graphics.

Here's some examples of SGPLOT code and survival curves

Thank you for the recommendation.

If you submit

ODS GRAPHICS ON;

before your PROC LIFETEST call, the procedure should produce a survival plot automatically.
