       trFormat.Root.Symbol.Shape.nVal = 9; // star
       trFormat.Root.Symbol.Size.nVal = 20;
       trFormat.Root.Symbol.EdgeColor.nVal = 5;
       trFormat.Root.Symbol.FillColor.nVal = 3;
       trFormat.Root.Color.nVal = -4; // to suppress line drawing between the point
       
       trFormat.Root.States.nVal = GOC_NO_SELECT; // so that it does not respond to mouse clicks
       mObj.ApplyFormat(trFormat, TRUE, TRUE);
