YAHOO ADVANCED CHARTS

Would be very useful a set of three buttons to instantly reposition the chart like this:

. A button to left justify the current period, keeping the current expansion of the chart (justify near left, not totally left)

. A button to center the hole session (ajusting the expansion to start the session near left and to finish ther sesion near right)

. A button to right justify the current period, keeping the current expansion of the chart (justify near right, not totally right)
