Plotten auf Charts js mehr als ein Datensatz

Question

Ich habe folgendes json:

[ 
{"periodo":"0","mes":"7","anio":"2015","montoIngreso":0,"monedaIngreso":"0","identifierIngreso":null,"montoGasto":0,"monedaGasto":"0","identifierGasto":null,"balance":0", 
{"periodo":"1","mes":"8","anio":"2015","montoIngreso":0,"monedaIngreso":"0","identifierIngreso":null,"montoGasto":0,"monedaGasto":"0","identifierGasto":null,"balance":0}, 
{"periodo":"2","mes":"9","anio":"2015","montoIngreso":0,"monedaIngreso":"0","identifierIngreso":null,"montoGasto":0,"monedaGasto":"0","identifierGasto":null,"balance":0}, 
{"periodo":"3","mes":"10","anio":"2015","montoIngreso":0,"monedaIngreso":"0","identifierIngreso":null,"montoGasto":0,"monedaGasto":"0","identifierGasto":null,"balance":0}, 
{"periodo":"4","mes":"11","anio":"2015","montoIngreso":0,"monedaIngreso":"0","identifierIngreso":null,"montoGasto":0,"monedaGasto":"0","identifierGasto":null,"balance":0}, 
{"periodo":"5","mes":"12","anio":"2015","montoIngreso":0,"monedaIngreso":"0","identifierIngreso":null,"montoGasto":0,"monedaGasto":"0","identifierGasto":null,"balance":0}, 
{"periodo":"6","mes":"1","anio":"2016","montoIngreso":0,"monedaIngreso":"0","identifierIngreso":null,"montoGasto":0,"monedaGasto":"0","identifierGasto":null,"balance":0}, 
{"periodo":"7","mes":"2","anio":"2016","montoIngreso":0,"monedaIngreso":"0","identifierIngreso":null,"montoGasto":0,"monedaGasto":"0","identifierGasto":null,"balance":0}, 
{"periodo":"8","mes":"3","anio":"2016","montoIngreso":0,"monedaIngreso":"0","identifierIngreso":null,"montoGasto":0,"monedaGasto":"0","identifierGasto":null,"balance":0}, 
{"periodo":"9","mes":"4","anio":"2016","montoIngreso":0,"monedaIngreso":"0","identifierIngreso":null,"montoGasto":0,"monedaGasto":"0","identifierGasto":null,"balance":0}, 
{"periodo":"10","mes":"5","anio":"2016","montoIngreso":0,"monedaIngreso":"0","identifierIngreso":null,"montoGasto":0,"monedaGasto":"0","identifierGasto":null,"balance":0},

{"periodo":"11","mes":"6","anio":"2016","montoIngreso":"5000","monedaIngreso":"2","identifierIngreso":"USD","montoGasto":175.56,"monedaGasto":"1","identifierGasto":"ARS","balance":4824.44}, 
{"periodo":"11","mes":"6","anio":"2016","montoIngreso":"5000","monedaIngreso":"2","identifierIngreso":"USD","montoGasto":"460810","monedaGasto":"2","identifierGasto":"USD","balance":-455810}, 
{"periodo":"11","mes":"6","anio":"2016","montoIngreso":"5000","monedaIngreso":"2","identifierIngreso":"USD","montoGasto":190.4448,"monedaGasto":"3","identifierGasto":"UYU","balance":4809.5552}, 
{"periodo":"12","mes":"7","anio":"2016","montoIngreso":219.318,"monedaIngreso":"1","identifierIngreso":"ARS","montoGasto":15.444,"monedaGasto":"1","identifierGasto":"ARS","balance":203.874}, 
{"periodo":"12","mes":"7","anio":"2016","montoIngreso":219.318,"monedaIngreso":"1","identifierIngreso":"ARS","montoGasto":"105002","monedaGasto":"2","identifierGasto":"USD","balance":-104782.682}, 
{"periodo":"12","mes":"7","anio":"2016","montoIngreso":"324342","monedaIngreso":"2","identifierIngreso":"USD","montoGasto":15.444,"monedaGasto":"1","identifierGasto":"ARS","balance":324326.556}, 
{"periodo":"12","mes":"7","anio":"2016","montoIngreso":"324342","monedaIngreso":"2","identifierIngreso":"USD","montoGasto":"105002","monedaGasto":"2","identifierGasto":"USD","balance":219340}] 

Und ich habe eine var mit den Etiketten:

["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"] 

Vom ersten json, es soll drei sein Datensätze „montoIngreso“ „montoGasto“ und „Balance“

Das Problem ist für einige der Etiketten, dass ich zwei Werte auf der json haben, zum Beispiel

anio: 2016 mes: 7 haben 4 Datensätze, also muss ich jede von ihnen hinzufügen, um 3 einzigartige Datensätze zu bilden

Wie kann ich das tun?

Danke!

Ok seine nichts Besonderes, aber:

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);
