如何将数据res从api推送到arrayToDataTable谷歌图表

Question

var nullArr = [null, 0, 0, 0, 0];
var chartData = [];

for (var i = 0; i < resData.length; i++) {
       var ownArr = [];
       var grArr = [];

       grArr.push(resData[i].Title, resData[i].GrValue1, resData[i].GrValue2, 0, 0);

       ownArr.push(resData[i].Title, 0, 0, 
       resData[i].OwnValue1,resData[i].OwnValue2);
       chartData.push(grArr, ownArr, nullArr);
    }
}

var data = google.visualization.arrayToDataTable([
   ['Year', 'A', 'B', 'A', 'B'],
   ['2012', 900, 390, null, null],
   ['2012', null, null, 100, 500],
   ['', null, null, null, null],
   ['2013', 1170, 440, null, null],
   ['2013', null, null, 200, 210],
   ['', null, null, null, null],
   ['2014', 1170, 440, null, null],
   ['2014', null, null, 200, 210],
]);

如何将数据推送到arrayToTable？我的阵列不正确。我的数据会发生什么。
