protected function mstrcolumnchart1_itemClickHandler(event:ChartItemEvent):void
{
// 如何取到单击时选中的值
}

<mstr:Model id="model1" baseModelKey="wsjg" templateDefn="r.[r:(1):(1);c:(1):(2)]"/>
</fx:Declarations>
<mstr:MstrColumnChart modelKey="model1" itemClick="mstrcolumnchart1_itemClickHandler(event)"/>
<mstr:MstrDataGrid x="435" y="10" id="mdmd"/>
</mstr:MstrApplication>

1、事件那边怎么取得这个图表 选中值。
2、怎么把最后一行那个 DataGrid 隐藏，然后单击时上面那图表事件弹出整个DataGrid 控件。求解。有高分！
