Thanks Friedrich, the -legend(order(1 2 3))- really does the trick! Michael

Michael, See -help legend order-. You can suppress legend entries by omitting them from the list. . sts graph, by(drug) addplot((pci -0.035 `a1' 0.5 `a1' -0.035 `a2' 0.5 `a2' -0.035 `a3' 0.5 `a3', lcolor(black) legend(order(1 2 3)))) yline(0.5, lpattern(dash)) Friedrich On Sun, Nov 2, 2008 at 6:14 PM, Michael McCulloch <mm@pinest.org> wrote:Thanks Martin! This works splendidly. May I ask: the legend adds another group entitled "y/yb", which seems to refer to the vertical lines created. Is there a way to suppress this? MichaelYou could also automate some of your calculations: ********** sysuse cancer.dta, clear stset studytime levelsof(drug), loc(levdrug) foreach lev of loc levdrug{ _pctile studytime if drug==`lev' loc a`lev'=r(r1) } sts graph, by(drug) addplot((pci -0.035 `a1' 0.5 `a1' -0.035 `a2' 0.5 `a2' -0.035 `a3' 0.5 `a3', lcolor(black))) yline(0.5, lpattern(dash)) ********** HTH Martin _______________________ ----- Original Message ----- From: "Michael McCulloch" <mm@pinest.org> To: "Statalist" <statalist@hsphsun2.harvard.edu> Sent: Sunday, November 02, 2008 4:04 AM Subject: st: Kaplan Meier plot: adding vertical line at median survivalGreetings, I'd like to plot a Kaplan Meier graph with a vertical line at the point of median survival, where the line begins at the x-axis and ends at the point where that vertical line intersects the survival curve. For example: sysuse cancer.dta stset studytime sts graph, by(drug) In this example, for drug2 median survival is at 13 months, and for drug3, at 25 months, so I'd . Is this possible within the -sts graph- command? I'm using v9.2 and so don't have the manual graphical editing features of v10. Thank you. -- Best wishes, Michael McCulloch* * For searches and help try: * http://www.stata.com/help.cgi?search * http://www.stata.com/support/statalist/faq * http://www.ats.ucla.edu/stat/stata/
