Proc Lifetest customising strata=panel curve

[Anita_n]

Hi all, 

I have a question about customising the proc lifetest curve for strata=panel. Which part of the proc lifetest template does that (I used this template on this link)   https://support.sas.com/documentation/onlinedoc/stat/ex_code/142/templft.html

Here is the code I used  for the normal curve without strata=panel. I wish to customise strata =panel the same way.

%ProvideSurvivalMacros
%let tatters = textattrs=(size=12pt weight=bold family='Calibri' color=cornflowerblue);
%let TitleText2 = "Overall Survival-Kaplan-Meier (RCC)"/&tatters; /* Change the title. */
%let nTitles = 1;
%let GraphOpts = DesignHeight=400px;
%let LegendOpts = ;
%let InsetOpts = ;

%let yOptions = label="survivalrate"
shortlabel= "survival" labelattrs=(size=10pt family='Calibri' ) tickvalueattrs=(size=8pt)
linearopts=(viewmin=0.2 viewmax=1 tickvaluelist=(0 .2 .4 .6 .8 1.0));
%let StepOpts = lineattrs=(thickness=2.0);


%let GraphOpts = DataContrastColors=(cornflowerblue moccasin darkblue darkred)
DataColors=(cornflowerblue moccasin darkblue darkred);

%let xOptions = label="Time(in days)" offsetmin=.05 linearopts=(viewmax=MAXTIME tickvaluelist=XTICKVALS
tickvaluefitpolicy=XTICKVALFITPOL)labelattrs=(size=10pt family='Calibri' ) tickvalueattrs=(size=8pt);

%let LegendOpts = title="AML" location=inside across=2 autoalign=(TopRight) ;

%let censored = markerattrs=(symbol=circlefilled size=5px );
%let censorstr = "(*ESC*){Unicode '25cf'x} censored" / textattrs=GraphValueText(family=GraphUnicodeText:FontFamily color=LightSlateGray);

proc template;
delete Stat.Lifetest.Graphics.ProductLimitSurvival / store=sasuser.templat;
delete Stat.Lifetest.Graphics.ProductLimitSurvival2 / store=sasuser.templat;
%CompileSurvivalTemplates

ods graphics on;
proc lifetest data=sashelp.BMT plots=(s(cb=hw test ATRISK strata=panel));
time T * Status(0);
strata Group;
run;
ods graphics off;

I will appreciate any help

Hello,

I do not know by heart which part of the proc lifetest template does that, but you may find below paper interesting and inspiring. You will probably find out the answer to your question yourself by reading this paper in-depth:

Paper 427-2013
Creating and Customizing the Kaplan-Meier Survival Plot in PROC LIFETEST
Warren F. Kuhfeld and Ying So, SAS Institute Inc.

If you don't want to read on a Sunday 😁, look at this video:

Good luck,

sorry, I have already seen these links but they couldn't help me further

Dear all,

I finally found out that the Template used to display the panels is Stat.Lifetest.Graphics.ProductLimitSurvivalPanel. I am tring  to customise this to the way I want 

but I will need a little bit help. I wish to have a different color for each panel. In my case I have four panels. I realise if I make changes to the section if PLOTCENSORED it affects the 4 panels  but I want to define for example these colours (blue green gray red) each one colour should affect the corresponding panel,  the following features: plotband, plotatrisk, plotlegend and group title.

I will also wish to change the x-axis label, I can't really findout I to do that. I will appreciate any help

Here is the code:
