，以產生對電網的單擊事件的圖表，我們使用監聽器selectionChange事件 選擇更改生成新的商店，其分配給條形圖

selectionchange: function (view, selections, options) { 
          //console.log(view, selections, options); 
          record = selections[0]; 
          //var v = record.get('Field1'); 
          //alert(''+v); 
          //alert(''+index) 
         // alert('hiiii') 


         record = selections[0]; 

         myData=[['Domestic',record.get('field1'),record.get('field2'),record.get('field3')], 
            ['Export',record.get('field4'),record.get('field5'),record.get('field6')], 
            ['Other',record.get('field7'),record.get('field8'),record.get('field8'), 
            ]] 

         }
