私は、次のJSON持っチャートJSの上に複数のデータセット

Question

をプロット：

[

を、私はラベルとVAR持っている：最初のJSONから

["2015-7", "2015-8", "2015-9", "2015-10", "2015-11", "2015-12", "2016-1", "2016-2", "2016-3", "2016-4", "2016-5", "2016-6", "2016-7"] 

を、3があるようになってデータセット「montoIngreso」「montoGasto」と「バランス」

問題は、例えば、ラベルのいくつかのために、私はJSONに2つの値を持っているということです

anio：2016 mes：7は4レコードですので、それぞれを3つの固有データセットに追加する必要があります

どのようにすればいいですか？

ありがとうございます！

その空想ではなく、[OK]を：

var valoresIngresos = new Array(labels.length).fill(0); 
var valoresGastos = new Array(labels.length).fill(0); 
var valoresBalance = new Array(labels.length).fill(0); 


for(var i=0;i<labels.length;i++) { 

    var fuentes = dataSource.filter(source=>(source.anio+"-"+source.mes) == labels[i]); 
    for(var j=0;j<fuentes.length;j++) { 

    valoresIngresos[i] = valoresIngresos[i]+parseFloat(fuentes[j].montoIngreso); 
    valoresGastos[i] = valoresGastos[i]+parseFloat(fuentes[j].montoGasto); 
    valoresBalance[i] = valoresBalance[i]+parseFloat(fuentes[j].balance); 
    } 

    } 

var ingresosDataset = { 
     label: "Ingresos", 
     data:valoresIngresos, 
     backgroundColor: "rgba(38, 185, 154, 0.31)", 
     borderColor: "rgba(38, 185, 154, 0.7)", 
     pointBorderColor: "rgba(38, 185, 154, 0.7)", 
     pointBackgroundColor: "rgba(38, 185, 154, 0.7)", 
     pointHoverBackgroundColor: "#fff", 
     pointHoverBorderColor: "rgba(220,220,220,1)", 
     pointBorderWidth: 1, 
    }; 

    datasets.push(ingresosDataset);
