Refresh a single chart in a series of charts

Question

Hi All,
    I have a screen with 4 charts. But I want to refresh each of the charts after a particular duartion.
For example the first chart should be refreshed after 1 minute.
The second chart should be replaced after 30sec...... And so on.........
Please help me to do this.
Thanks

You can add timers to each of your charts explicitly. Set the duration as desired in each of these timers ( 60000 milli seconds  for 1st chart and 30000 for the second chart ). You will have to add event handlers for the timer complete event (TimerEvent.TIMER). In these event handlers call your http service or refresh your charts by updating the chart's dataprovider.
example code below :
<mx:Script>
        <![CDATA[
    private var timer:Timer;
            private function init():void{
                    timer = new Timer(60000);    // 1 minute
                    timer.addEventListener(TimerEvent.TIMER,refershGraph);
                    timer.start();
    private function refershGraph(event:TimerEvent):void{
          // update the dataprovider of your chart or call your httpservice here
         // reset the timer and start it again         
          timer.reset();           
          timer.start();   
]]>
    </mx:Script>
Cheers
