重新整理数据图表

Question

我需要您的帮助来解决我的数据重组问题，我正在尝试使用带有来自xml链接的动态数据的chartjs创建图表，下面显示的代码有效，但并不是我想要的确切方法。 在我目前的情况下，我得到“例如” ChefProjet = 10，ChefProjet = 7，ChefProjet = 7，ChefProjet = 7，因此ChefProjet重复了四次，但我只想显示一次ChefProjet，它等于31（10+ 7 + 7 + 7），您可以在图片的链接中看到图表。 ↓

成功了，这是解决方案：

    $.ajax({
    url: _spPageContextInfo.webAbsoluteUrl + add2,



    method: "GET",
    headers: { "Accept": "application/json; odata=nometadata" },
    success: function (data) {

        if (data.value.length > 0) {

           var reducedObject = {};
            for (var i = 0; i < data.value.length; i++) {
                    if (!reducedObject[data.value[i].ResourceName]) {
                        reducedObject[data.value[i].ResourceName] = 0;
                }
                reducedObject[data.value[i].ResourceName] += parseInt(data.value[i].AssignmentWork);
            }
