extjs里如何调整columns里的列宽

其实不要想得太复杂，可以直接给column设置width属性来改变宽度。

如果要设置自适应列宽的话可以参考以下：

var grid = new Ext.grid.GridPanel({

title : ‘表格列自动分配宽度’,

columns : [

{header : ‘id’,dataIndex:’id’,width: 200},

{header :’name’,dataIndex:’name’}

store : 数据源

});

EXTJS3.0如何画柱状图

用ext3.0实现的，我测试的整个文件如下

//以上的3个文件的引用很重要，要和你自己的相关路径对应。

怎么用ExtJs 的chart做出这样的奖金池变化图：

这是标准的堆叠图

给你来个例子研究一下

Ext.define(‘ChartsKitchenSink.view.charts.column.Stacked’, {

extend: ‘Ext.Panel’,

xtype: ‘stacked-column’,

initComponent: function() {

var me = this;

this.myDataStore = Ext.create(‘Ext.data.JsonStore’, {

{ month: ‘Feb’, data1: 20, data2: 37, data3: 36, data4: 5 },

{ month: ‘Mar’, data1: 19, data2: 36, data3: 37, data4: 4 },

{ month: ‘Apr’, data1: 18, data2: 36, data3: 38, data4: 5 },

{ month: ‘May’, data1: 18, data2: 35, data3: 39, data4: 4 },
