Superimposing multiple survival curves on one graph using Proc PHReg SAS 9.4

[joesmama]

Hello,

New to SAS. Trying to plot multiple survival curves on one graph using PHREG. I've tried the overlay option

my model is set up as follows:

proc phreg data=grands alpha=0.05 PLOTS(OVERLAY range=(0, 200)) = (SURVIVAL);
class grade racen gender marst stage;
model survivem*cs_vital(0) = grade gender marst racen;
by stage;
run;

I'd simply like to see three different survival curves (one for each stage)  on  one graph. As of now, they are printing separately. 

Thanks in advance for your help.

BY STAGE means you have a different regression for each STAGE and then each analysis is handled independently. Do you need STRATA instead?

If BY is correct, you'll need to use the raw data and create the graphs afterwards using SGPLOT. There are a lot of examples of this online.
