extjs ColumnChart设置不同的颜色实现代码_extjs

复制代码 代码如下:

Ext.onReady(function(){
//定义store
var chartStore = new Ext.data.JsonStore({
root:'root',
fields:[
{name:'ne',type:'string'},//网元
{name:'confine',type:'int'},//阀值
{name:'bill',type:'string'}//工单数
],
sortInfo:{field: 'bill', direction: 'ASC'}
});
//测试数据
var obj={
root:[
{ne:'网元一',confine:80,bill:150},
{ne:'网元二',confine:150,bill:140},
{ne:'网元三',confine:180,bill:160},
{ne:'网元五',confine:120,bill:180},
{ne:'网元六',confine:165,bill:13},

{ne:'网元九',confine:33,bill:113},

}
//载入数据
chartStore.loadData(obj);
//pushlet 回调函数
window.onData = function (event) {
//alert(event.get("data1"));
var obj1 = eval('('+event.get("data1")+')');
//obj=obj1;
//chartStore.loadData(obj);
}
// 系统属性定义列数据模型
