Many thanks, Nick - that works very well.
yes, the K-M curves were all above 0.8
PS - no one has yet replied to my age-adjust or age-standardise query for
incidence rates. I am sorry i posted the question twice - it was because i
was presenting it in two different ways, to explain it better the second
time
If you or anyone else has an idea of how to do that, i would be very
grateful. I have been stuck with that query for a little while now. If
anyone wants the query re-sent pls let me know, and i can send it to just
the one person, rather than whole group.
Many thanks
Nita

Subject: st: RE: yscale/range to plot
Sometimes you have to force the labels
as well. That is, -ysc()- is perhaps being ignored
because the default axis labelling contradicts
it.
So try adding
yla(0.8(0.05)1)
to your command.
Presumably your Kaplan-Meier curves are all above 0.8.
