I want to create a chart of how many tasks are in a given Schedule State during the length of the sprint. Is it possible to call WsapiDataStore on each day?

您正在寻找的是

What you are looking for is a lookback Snapshot Store , using the Lookback API - this allows you to specify a date or a point in time that you want to query by.

典型用法如下:

    Ext.create('Rally.data.lookback.SnapshotStore', {
        pageSize : 10000,
        fetch    : ['fetch'],
        filters  : [{
            property : '__At',
            value    : 'current'
        },{
            property : '_ItemHierarchy',
            value    : 'HierarchicalRequirement'
        }]
    }).load({
        callback : function(records) {
            Ext.Array.each(records, function(record) {
                // do something with each record
            });
        }
    });
