如何在ExtJs中向下钻取图表

标签： javascript extjs4.1 extjs4.2 extjs-mvc

这是我的示例应用程序，其中我有一个barChart和一个雷达和四个饼图。我必须向下钻取barChart。我以前开发过一个应用程序，我没有使用MVC，我能够钻 - 现在我正在使用EXTJS MVC我无法理解我应该把钻取代码放在哪里..这是我之前没有MVC的barChart .. 

window.weekWiseData = function(n, floor){
 var data = [],i;
  var weeks = ['Week1','Week2','Week3','Week4'];
  floor = (!floor && floor !== 0)? 20 : floor;
for (i = 0; i < (n || 4); i++) {
   data.push({
       name: weeks[i],
       data1: Math.floor(Math.max((Math.random() * 100), floor)),
       data2: Math.floor(Math.max((Math.random() * 100), floor)),
       data3: Math.floor(Math.max((Math.random() * 100), floor)),
       data4: Math.floor(Math.max((Math.random() * 100), floor)),
       data5: Math.floor(Math.max((Math.random() * 100), floor)),
       data6: Math.floor(Math.max((Math.random() * 100), floor)),

       data8: Math.floor(Math.max((Math.random() * 100), floor)),
       data9: Math.floor(Math.max((Math.random() * 100), floor))
    });
 }
   return data;

var barWeekData;


window.dayWiseData = function(n, floor){

   data.push({
       name: Ext.Date.dayNames[i % 7],
       data1: Math.floor(Math.max((Math.random() * 100), floor)),
       data2: Math.floor(Math.max((Math.random() * 100), floor)),

这是我没有MVC的barChart现在我用MVC结构创建了应用程序。这是我的Controller文件.... 

Ext.define('Gamma.controller.ControlFile', {

extend : 'Ext.app.Controller',

//define the stores
stores : ['BarColumn','RadarView','VoiceCallStore','SMSCallStore','MMSCallStore','GPRSUsageStore'],


 models :     ['BarCol','radar','VoiceCallModel','SMSCallModel','MMSCallModel','GPRSUsageModel'],

    views : ['BarColumnChart','LineChart','RadarChart','VoicePie','SMSPie','MMSPie','GPRSPie'],  

refs: [{
ref: 'radar',
selector: 'radarChart'
},{
ref: 'sms',
selector: 'smsPie'
},{
ref: 'gprs',
selector: 'gprsPie'
},{
ref: 'mms',
selector: 'mmsPie'
},{
ref: 'voice',
selector: 'voicePie'
}],

initializedEvents: false,
init: function() {
this.control({
    '#barColumnChart': {
        afterlayout: this.afterChartLayout
    }
});
},
afterChartLayout: function(){
var me=this;
if(this.initializedEvents==true) return;
this.initializedEvents=true;
Ext.getCmp('barColumnChart').series.items[0].on('itemmousedown',function(obj){






    // alert(obj.storeItem.data['source']+ ' &' + obj.storeItem.data['count']);

    // var barData=obj.storeItem.data['source']+ ' &' + obj.storeItem.data['count'];
    var source=obj.storeItem.data['source'];
    var count=obj.storeItem.data['count'];
    me.dataBaseCall(source,count);
});

这是我的查看档案......

Ext.define('Ext.chart.theme.Fancy', {

    },
    axisLabelBottom: {
        fill: baseColor

这是我的商店.. 

 Ext.define('Gamma.store.BarColumn', {

model: 'Gamma.model.BarCol',
autoLoad: true,
pageSize: 100,
id:'BarColumn',


proxy: {

reader: {
    type: 'json',
    root: 'topList',
    totalProperty: 'totalCount',
    successProperty: 'success'
}
  }

});

有一个Highcharts插件

http://www.sencha.com/forum/showthread.php?93669-Highcharts-adapter-and-plugin-for-ExtJS

或未记录的点击事件

http://druckit.wordpress.com/2013/03/19/ext-js-and-sencha-touch-charts-drill-down/

或根据其他地方的点击重新加载数据

虽然我还没有尝试过。
