Drazen,
This is an ellipse centered at [x0,y0]
x0=900;y0=100;a=20;b=30;x=Cum(1);
// b^2*(x-x0)^2+a^2*(y-y0)^2=(a*b)^2
y=y0+sqrt(((a*b)^2-b^2*(x-x0)^2)/a^2);
Plot(y,"",1,1);
y=y0-sqrt(((a*b)^2-b^2*(x-x0)^2)/a^2);
Plot(y,"",1,1);
Plot(y0,"",1,1);Plot((Cum(1)==x0)*(y0+2*b),"",1,2);
Note that x0 is counted from the beginning of your data.
