Thank you kindly Michael! On Feb 11, 2010, at 8:48 PM, Michael Norman Mitchell wrote:

Dear MichaelIf I understand your last message, you want to be able to changethe placement of the "log rank P= 3.67" text. If so, you can controlthat by the coordinates specified in the "text()" option. Forexample, if you do this...sysuse cancer.dta, clear stset studytime drop if drug==3 sts test drug local chi_res logrank P = `=round(r(chi2), .01)'sts graph, by(drug) risktable text(.95 28 "`chi_res'", size(small)col(red))The text will be displayed in the upper right corner, because thecoordinates are y=.95 x=28. You can fiddle with those (Y,X) valuesto place the text whereever yo like. I hope that helps,Michael N.

This gives me the idea. May I ask:* regardless of what place option I use: ne, se, nw, sw, etc.,they all put the text box in the lower left corner.
