Hi:
I don't know much about PROC LIFETEST, but there is a Tech Support note that seems to contain a lot of info on customizing PROC LIFETEST graphs or reproducing them with PROC GPLOT (which does have a lot of customization ability).
In addition, PROC LIFETEST is one of the procs that supports ODS GRAPHICS (which is still experimental in SAS 9.1.3 -- if you want to adjust the axis for ODS GRAPHICS output, then you might want to contact Tech Support for help in that regard.

here's an example of how you'd use PROC LIFETEST with ODS GRAPHICS:
[pre]
ods html path='c:\temp' (url=none)
gpath='c:\temp' (url=none)
file='lifetest.html'
style=statistical;
ods graphics on/ imagefmt=static;
goptions reset=(symbol axis);
symbol1 c=blue; symbol2 c=orange;
proc lifetest data=Exposed outsurv=outsurv
plots=(s,lls) noprint;
time Days*Status(0);
strata Treatment;
run;
ods graphics off;
ods html close;
[/pre]
(based on the data in this example but using ODS Graphics instead of GPLOT
