Hi all,

 I have this graph that is to show the traffic throughput. It updates every 
2 secs. What should be the correct way to do this so that the axes can 
update dynamically, i.e it progress from right to left, showing the time. 
The diagram below shows the x-axis.


 now: ---+----+----+----+----
        20   22   24   26

later: ---+----+----+----+----
         22   24   26   28


Ricky
