Michael The placement() suboption's arguments (ne, se etc) are relative to the _point_ you nominate as the #y #x arguments of the main text() option. In this case we had text(.05 5...) and the placement was ne , so the box was sited to the northeast (above and to the right) of of the point defined by y=0.05 and x=5. If you want the text box elsewhere, you will need to change the #y and #x specs. As far as box size is concerned: sysuse cancer.dta, clear stset studytime drop if drug==3 sts test drug local chi_P logrank P = `=round(chi2tail(r(df),r(chi2)), .01)' sts graph, by(drug) risktable text(.05 5 "`chi_P'", place(ne) box size(small) col(red) width(80) height(40)) ... though admittedly more care with the height() and width() option might be warranted.

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. I've read -help compassdirstyle- and * bexpand also doesn't expand the size of the box. Michael On Feb 11, 2010, at 8:05 PM, Philip Ryan wrote: > Michael > > I note you wanted a "window".
