Plot chart problem

Question

Hi experts,
    In plotchart using cirlcular item renderer am getting full details.But instead of that one using customItemRenderer am unable to get full details.This is my customItemRender(CirlceFileRenderer ) action script class file
package
    import flash.display.Graphics;
    import mx.charts.series.items.PlotSeriesItem;
    import mx.core.IDataRenderer;
    import mx.skins.ProgrammaticSkin;
    public class CirlceFileRenderer extends ProgrammaticSkin implements IDataRenderer
        public function CirlceFileRenderer()
        private var _chartItem:PlotSeriesItem;
        public function get data():Object
            return _chartItem;
        public function set data(value:Object):void
            _chartItem = value as PlotSeriesItem;
            invalidateProperties();
        override protected function updateDisplayList(unscaledWidth:Number,unscaledHeight:Number):void
            super.updateDisplayList(unscaledWidth, unscaledHeight);
            var g:Graphics = graphics;
            g.clear();
            var col:Number = 0;
            var x:Number = 0;
            var y:Number=0;
            //if(_chartItem!=null)
            var obj:Object = _chartItem.item as Object;
            //col = getColor(obj.Color as Number);
            x= obj.Xdata as Number;
            y=obj.Ydata as Number;
            g.beginFill(col);
            trace("X :"+x+" Y :"+y);
            trace("_chartItem.x:"+_chartItem.x+" _chartItem.y :"+_chartItem.y);
            g.drawCircle(_chartItem.x,_chartItem.y,1);
            //g.drawCircle(x,y,1);
            //g.drawRect(_chartItem.x,_chartItem.y,unscaledWidth,unscaledHeight);
            // g.drawRect(x,y,1,2);
            g.endFill();
        public function getColor(x:Number):Number   
            if(x < 0.0)
                return 0x000000;
            else if (x < 0.125)
                return 0x000088;
            else if (x < 0.375)
                return 0x0000FF;
            else if (x < 0.625)
                return 0x00FFFF;
            else if (x < 0.875)
                return 0xFFFF00;
            else if (x <= 1.0)
                return 0x880000;   
            else
                return 0xFFFFFF;   
Flex action script code is like this:
private function handleResult(event:ResultEvent):void
                temparray = event.result as Array;
                for(var i:int =0;i<256;i++)
                    var ta:Array = new Array();
                    var ar:Array = new Array();
                    ar = temparray[i];
                    for(var j:int = 0;j<288;j++)
                    //    trace("a["+i+"]["+j+"] -:"+ar[j]+" Color:"+(Math.abs(ar[j])-131) / 20);
                        ta.push({Xdata:i,Ydata:j,Color:(Math.abs(ar[j])-131) / 20  });
                    var ps:PlotSeries = new PlotSeries();
                    ps.xField = "Xdata";
                    ps.yField = "Ydata";
                    //ps.radius = 1;
                    ps.setStyle("itemRenderer",new ClassFactory(CirlceFileRenderer));
                    ps.dataProvider = ta;
                    newarr.addItem(ps);
                chart.series = newarr.toArray();       
Am unable to find the problem.I didn't get full details in plot chart.
Please tell me this is urgent requirement....

Hi,
what info you didn't get?
try this
public function set data(value:Object):void
            _chartItem = value as PlotSeriesItem;
          super.data = value;
            invalidateProperties();
