I am using SAS 9.3 ( recently moved from SPSS to SAS.).
I am running KM survival curve and my questions is slightly "cosmetic" .
I want the KM survival lines thicker (double thicker than default) and different colors than default. Below is the code.
In output, I am having KM survival plot in perfect shape but not with the thickness and line colors I wanted.
Your help is much appreciated.
goptions lfactor=5 vsize=5 hsize=7 ftext=swissb noprompt;
symbol1 c=black v=point h=1 i=steplj l=1;
symbol2 c=blue v=point h=1 i=steplj l=1;
symbol3 c=red v=point h=1 i=steplj l=1;
symbol4 c=orange v=point h=1 i=steplj l=1;
order=(0 to 7 by 1)
axis2 label=(a=90 'Proportion Free from Death')
order=(0 to 1 by 0.2)
proc lifetest data=dt plots=survival(atrisk (maxlen=13 outside(0.15)));
time KM_years * censor(0);
strata abc /order=internal;

One way would be to use the ODS table to output the survival data in a SAS table, then use PROC (S)GPLOT to plot it.
If you run the ODS TRACE ON; command before your proc lifetest. in the log file you will get the SAS tables associated with this PROC.
Then run ODS TRACE OFF to stop getting the information in the log;

Here is a blog article on this. In the STEPPLOT, change the thickness of the line by using the following option: STEPPLOT x= y= / LINEATTRS=(THICKNESS=2).

You are working with ods graphics off and trying to apply xchanges to classical sas graphs
but there is another manner of working i shall try to explain here
(working by default for 9.3.2 as ods graphics on; is active)
Lets take few similar code ods graphics must be open !!!!!
first line open the sge possibility
second line rtestrict the work to only the graph plot (without any sas graph instructions):
ods html sge=on;
ods select lifetest.survivalplot;
proc lifetest data=muco.survie_cohorte_sexe graphics plots=(s) cs=none width=1 ;
time duree_vie*censure(0) ;
strata cohorte_sexe ;
survival out=muco.sortie_survie_cohortes_sexe_mkm ;
title 'Analyse de survie par cohorte de sexe 1' ;
title2 'Methode Kaplan-Meier' ;
ods select all;
you have some results 2 thin lines and colored in blue and red
Now open the sge sas graphic editor
and you can change the style from statistical to analysis
and the thickness of your graphic and a lot of others details on the two types of line: scatter and survival
with a right clic on a line
and saving it in png under a new name
You have a lot of different examples on survival code on pages 124-137 in my text
BUT it is written in french
Some texts in english are indicated here :
about the SGE
Sanjay Matange ODS GRAPHICS EDITOR http://www.nesug.org/Proceedings/nesug08/po/po24.pdf
about survival see here a very good resume of ways
Finally you have also the ods graphical designer as clic click solution see visual pages 138 to 141
the learning process could take time as you are starting in sas coming from spss.
a lot of sas users are not knowing yet what is explained here.
