I am facing problem while trying to get Altered value from Gauge in runtime, i am using following code and i am getting undefined for "dialValue" .

function FC_ChartUpdated(DOMId)

{

         if (DOMId=="ChId1")

         {

            var chartRef = getChartFromId(DOMId);

            var dialValue = chartRef.getData(0);

           alert(dialValue);

          getNewContent(Math.floor(dialValue));

         }

}
