如何通过时间戳将角度过滤器数据分组？

Question

我的MVC返回此JSON

[
{
    "$id":"1",
    "Tags":
        [
            {"$id":"2","Values":
                            [
                                {"$id":"3","Tag":{"$ref":"2"},"ID":4,"TagID":1,"Value1":5.00,"TimeStamp":"2015-10-26T15:23:50","Quality":1,"Tags_ID":1},
                                {"$id":"4","Tag":{"$ref":"2"},"ID":7,"TagID":1,"Value1":4.00,"TimeStamp":"2015-10-26T15:25:50","Quality":2,"Tags_ID":1}
                            ],"Reports":[{"$ref":"1"}],"ID":1,"Name":"0101WT370/WT.VALUE","Type":null,"Archive":null,"Server":null,"Created":null,"Edited":null},
            {"$id":"5","Values":[],"Reports":[{"$ref":"1"}],"ID":2,"Name":"0101WT371/WT.VALUE","Type":null,"Archive":null,"Server":null,"Created":null,"Edited":null},
            {"$id":"6","Values":[],"Reports":[{"$ref":"1"}],"ID":3,"Name":"0101WT395/WT.VALUE","Type":null,"Archive":null,"Server":null,"Created":null,"Edited":null},
            {"$id":"7","Values":[],"Reports":[{"$ref":"1"}],"ID":4,"Name":"0101WT396/WT.VALUE","Type":null,"Archive":null,"Server":null,"Created":null,"Edited":null}

        ],
    "ID":3,"Name":"A"
},
{
    "$id":"8",
    "Tags":[],"ID":4,"Name":"B"
}
]

我希望winth Angular按时间戳分组值 - 每小时，每天或每月

我想要每天的结果示例：

标签|时间戳|价值|

Tag1中| 26-10-2015 | 4.5 =（9/2）= value1 + value2 / count

你能给我任何建议吗？

I found this where give me something like way to start from :)

尝试以下代码：

<强> JAVASCRIPT

    function sortTimeStamp(obj) {
    for(i=0; i<obj.length;i++) {
        for(z=0; z<obj[i].Tags.length;z++) {
            for(y=0; y<obj[i].Tags[z].Values.length;y++) {
                obj[i].Tags[z].Values.sort(function (a, b) {
                  return new Date(b.TimeStamp).getTime() - new Date(a.TimeStamp).getTime();
                });
            } 
        }  
    }
    return obj;
}

var myObj = [
