What is not working, I found that using a canvas works fine, BUT you have to redraw before you see your changes, ie
with ImageScrollBox.Graphic.Canvas do
begin
Pen.Color := gridcolor;
Polyline([ul,ur,lr,ll,ul]);
moveto(startx+offset,startY+offset+ dayY-20);
lineto(startx+width-offset,startY+offset+ dayY-20 );
end;


will work, but the box will not actually be visible until you redraw the image with

ImageScrollBox.Redraw(True);
