        <script type="text/javascript" src="../Extjs4/exporting.js"></script>

1.第一步骤： 在html文件中定义适配器 如下：  

[html] view plaincopy

1.      <style type="text/css">  
2.             .container {  
3.                 width: 1000px;  
4.                 height:550px;  
5.                 display: none;  
6.             }  
7.         </style>  
8.           
9.   
10.   
11.   
12.       <div id="containerId">  
13.             <div id="container1" class="container"></div>  
14.       </div>  

2. 第二步骤 准备 highcharts(柱状图)  工作 ，这个动作可以用方法加以调用  如下，

[javascript] view plaincopy

1.     <pre name="code" class="javascript">     var containerId = "#container1";  
2.      $(containerId).css('display','block');</pre> <br>  
3. <pre name="code" class="javascript">     window.panelStore2 = Ext.create('Ext.data.Store', {  
4.           fields:['name',{name:'preStatics',type:'int'},'mypercent'],  
5.           proxy: {  
6.                 type: 'ajax',  
7.                 url: extPath+'/center!getDetailByType.action?random='+new Date().getTime()+''+'&type=2',  
8.                 reader: {  
9.                     type: 'json',  
10.                     root: 'humresData',  
11.                     totalProperty: 'totalCount'  
12.                 }  
13.            },  
14.           autoLoad: false,  
15.           sorters:[{  
16.             property:"name",  
17.             direction:"asc"  
18.           },{  
19.                 property:"preStatics",  
20.                 direction:"asc"  
21.           }],  
22.           listeners:{  
23.                  beforeload:function(store,records,successful,operation,opts){  
24.                       msgTip = Ext.MessageBox.show({  
25.                           title:'提示',  
26.                           closable:false,  
27.                           width : 250,  
28.                           msg:'页面统计信息刷新中,请稍后...'  
29.                       });  
30.                  },  
31.                 load:function(store,records,successful,operation,opts){  
32.                         if(successful){  
33.                             var years = [];  
34.                     var values = [];  
35.                     store.each(function(rec){  
36.                     years.push(parseInt(rec.get('name')));  
37.                         values.push(parseInt(rec.get('preStatics')));  
38.                      });  
39.                     initCharts1(years,values);  
40.                             Ext.Msg.alert('提示','数据加载成功!');  
41.                             msgTip.hide();  
42.                               
43.                         }else{  
44.                               
45.                             Ext.Msg.alert('提示','数据加载失败!');  
46.                             msgTip.hide();  
47.                         }  
48.                           
49.                     }  
50.           }  
51.     });  
52.     //--------------------------------------------------------------------------------------//  
53.      function  initCharts1(years,values){  
54.           var chart = new Highcharts.Chart({
