This should work too, in the same example. line basesurvest* _t, connect(J ..) sort legend(order(1 "1" 2 "2" 3 "3")) Nick njcoxstata@gmail.com On 18 April 2013 10:58, Tim Evans <Tim.Evans@wmciu.nhs.uk> wrote: > Can you run -stcox- with and estimate the basesurv.

How do I overlay the two plots (containing 2 curves, because stcurve, by variable command used) into one single graph)? I tried graph combine (not what I want) and addplot (does not seem to work). * * For searches and help try: * http://www.stata.com/help.cgi?search * http://www.stata.com/support/faqs/resources/statalist-faq/ * http://www.ats.ucla.edu/stat/stata/
