Changing Line colors in KM plot

sfo — Fri, 19 Oct 2018 23:55:27 GMT

Hi,

Is there a way I can specify particular colors in KM plot using proc lifetest?

I tried

%ProvideSurvivalMacros %let GraphOpts = DataContrastColors=(green red blue) DataColors=(green red blue); %CompileSurvivalTemplates

from the link https://support.sas.com/documentation/onlinedoc/stat/131/kaplan.pdf

but it doesn't seem to work.

Hi:
Did you follow the instructions on page 799 to download and store the macro code in a temporary file? If you followed the instructions and it's not working for you, then you'll want to open a track with Tech Support on this.

The surv macro should work. Please post your full code and and the log. If you cannot use your real data please feel free to use a dataset from the documentation or sashelp.heart

Thanks for your help.

This is the log:

ERROR: Template 'Stat.Lifetest.Graphics.ProductLimitSurvival' was unable
to write to template store!
ERROR: Template 'Stat.Lifetest.Graphics.ProductLimitSurvival2' was unable
to write to template store!

and this is how I am doing in my code:

ods pdf file="&dir\OAK_KM_&fn._Plot_%sysfunc(date(),yymmdd10.).pdf" style=HMTLBlue;
ods listing close;
ods graphics on;
goptions xmax=5 ymax=4 xpixels=1500 ypixels=1200;

%ProvideSurvivalMacros
%let GraphOpts = DataContrastColors=(green red blue)
DataColors=(green red blue black);
%CompileSurvivalTemplates

ODS EXCLUDE ProductLimitEstimates;

proc lifetest data=OS_Titer_KM plots=survival(atrisk);
time TIME*censor(1);
strata A;
run;

Try deleting the templates and try again?

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

Also, I tried to run your code as is and there were some weird issues, not sure if that was introduced from copy/pasting from here or from documentation. Either way, the code works when I typed it out manually step by step again.

I tried again and getting the attached error log and below is my code:

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

data _null_;
%let url = //support.sas.com/documentation/onlinedoc/stat/ex_code/131;
infile "http:&url/templft.html" device=url;
file 'macros.tmp';
retain pre 0;
input;
if index(_infile_, '</pre>') then pre = 0;
if pre then put _infile_;
if index(_infile_, '<pre>') then pre = 1;
run;
%inc 'macros.tmp' / nosource;

%ProvideSurvivalMacros
%let GraphOpts = DataContrastColors=(green red blue black)
DataColors=(green red blue black);
%CompileSurvivalTemplates
ods graphics on;

proc lifetest data=data
plots=survival(cb=hw test atrisk(outside maxlen=13));
time TIME*censor(1);
strata T_Titer;

ods graphics off;

I think you need to contact tech support now. That shouldn't happen. If you're working with SAS UE that may be part of it, because the SASuser library isn't writeable in that edition.
