How do you define "the appropriate coordinates"?

Please find below an example of string placement

t=linspace(0,2*%pi,100);
clf;plot(t,sin(t))
//now I want to draw a string  at different locations
str="Scilab";
rect=xstringl(0,0,str);
//the lower left corner of the rectangle surrounding the string 
positionned at the (3,sin(3)) point
plot(3,sin(3),'xr')
xstring(3,sin(3),str)
e=gce();e.box='on';
//the upper left corner of the rectangle surrounding the string is 
positionned at the (3,sin(3)) point
plot(2,sin(2),'xr')
xstring(2,sin(2)-rect(4),str)
e=gce();e.box='on';
