如何使用APP SDK2.0构建图表进行迭代？

Question

我正在尝试为拉力赛创建自定义应用。

Iteration defects by severity and below is my code.

var startdate;
var enddate;
var iterationid;
Ext.define('CustomApp', {
    extend: 'Rally.app.App',
    componentCls: 'app',
    launch: function() {
        var that = this;
        that.getCurrentIteration(function(iterations){
             console.log("getting iteration object");
             startdate = _.map(iterations,function(i){return i.get("StartDate")});
             enddate = _.map(iterations,function(i){return i.get("EndDate")});
             iterationid = _.map(iterations,function(i){return i.get("ObjectID")});
             that._load();
        });
    },

     getCurrentIteration:function ( callback ) {
        var today = Rally.util.DateTime.toIsoString(new Date());
        Ext.create('Rally.data.wsapi.Store', {
            model: 'Iteration',
            autoLoad: true,
            context : {
                projectScopeDown : false   
            },
            filters: [
                {
                    property: 'EndDate', operator: '>=', value: today
                },
                {
                    property: 'StartDate', operator: '<=', value: today
                }
            ],
            listeners: {
                load: function(store, data, success) {
                    callback(data);
                }
            },
            fetch: true
        });
    },

    _load:function(){
        this.defineCalculator();
        this.makeChart();
   },    

    defineCalculator: function(){

                ];  
                return metrics;
            }
        });
    },

    makeChart: function(){
        if (this.down('#myChart')) {
                this.remove('myChart');
        }
        console.log(enddate[0])

            xAxis: {
                tickInterval: 1,
                labels: {
                    formatter: function() {
                        var d = new Date(this.value);
                        return ""+(d.getMonth()+1)+"/"+d.getDate();
                    }
                },
                title: {
                    text: 'Date'
                }
            },
            yAxis: [
                {
                    tickInterval: 1,
                    title: {
                        text: 'Count'
                    }
                }
            ]
            }
    }   

});

我现在正在获取数据并且我设法在图表上显示它，但问题是数据显示甚至未来日期，即，我当前的迭代是从13到26，理想情况下它应该显示数据今天是13,14和15，但它显示了所有日期..任何人都可以帮助我限制逻辑缺失的地方。

Thanks,
