mousemove on a chart. Basically i have to send the hit data of
relevent series to LegendItem component. I am not sure how to
communicate to legenditem 

Thx in advance

================================ code for call to component
================================ 
For each dynamically created series

series1.setStyle("lineStroke",seriesStroke);
var legendMarkerRenderer:ClassFactory = new ClassFactory(ChartLegendItem);
                        
series1.setStyle("legendMarkerRenderer",legendMarkerRenderer);

=======================code of ChartLegendItem ===============
package icc.charting.component {
        
        import mx.charts.LegendItem;
        import mx.controls.CheckBox;
        
        public class CheckBoxLegendItem extends LegendItem {
                
                private var cb : CheckBox;
                
                override protected function createChildren():void {
                        super.createChildren();
                        
                        cb = new CheckBox();
                        cb.selected = true;
                        addChild( cb );
                }
                
                override protected function measure():void {
                        super.measure();
                        // add some extra space for the checkBox
                        measuredWidth += 30;
                }
                
                override protected function 
updateDisplayList(unscaledWidth:Number,
                                                                                
          unscaledHeight:Number):void {
                        super.updateDisplayList( unscaledWidth, unscaledHeight 
);
                        
                        //move the checkbox to the right
                        cb.move( unscaledWidth - 30, 0 );
                }
                        
        }
}
