mx: series

[JunkieIII]

Я строю :

<mx:LineChart x="10" y="0" id="linechart1" width="900" height="392" dataProvider="{medalsAC}" showDataTips="true">
		<mx:backgroundElements>
               	   <mx:GridLines direction="both"/>
            	</mx:backgroundElements>
 
            	<mx:series>
			<mx:LineSeries displayName="Jan" yField="YEAR" xField="Jan" />
			<mx:LineSeries displayName="Feb" yField="YEAR"  xField="Feb"/>
			<mx:LineSeries displayName="Mar" yField="YEAR"  xField="Mar"/>
 
		</mx:series>
			</mx:LineChart>
	<mx:DataGrid id="myGrid" x="100" y="430" width="650" height="290" editable="true" dataProvider="{dataSPtt}">
      				<mx:columns>
      				   <mx:DataGridColumn headerText="Рік" dataField="Year" />
       				   <mx:DataGridColumn headerText="Січень" dataField="Jan" />
       				   <mx:DataGridColumn headerText="Лютий" dataField="Feb" />
       				   <mx:DataGridColumn headerText="Березень" dataField="Mar" />
       				 </mx:columns>
	 </mx:DataGrid>
<mx:Legend direction="vertical" dataProvider="{linechart1}" x="750" y="250"/>

но по прежнему ничего не строиться((((
