Ext chart读xml数据

一定要加type: 'int'，否则不显示

var store = new Ext.data.XmlStore({         
      url: 'test1.xml', 
      record: 'test',
      fields:[{name:'name'},{name:'members', type:'int'}]
});
store.load();

 柱状：

var columnChart = new Ext.chart.ColumnChart({   
    store: store,   
    //url:'../ext-3.0-rc1/resources/charts.swf',   
    xField: 'framework',   
    yField: 'users'  
});  

 饼状：

var pieChart = new Ext.chart.PieChart({   
    store: store,   
    dataField: 'users', //information to display in the chart   
    categoryField : 'framework' //tags or categories   
});  

 线状：

var lineChart = new Ext.chart.LineChart({   
    store: store,   
    xField: 'framework',   
    yField: 'users'  
});
