Array not being created correctly

I have a AngularJS variable that stores a whole jSON that I load, the jSON data looks like this:

{
    "Products": "Pimenta Vermelha muito boa",
    "Product_Code": "XXXXX",
    "RTV": "Alisson Acioli",
    "Regional": "Sudeste",
    "Cliente": "AGRO",
    "Estado": "MG",
    "Pricing_Zone": "XXX",
    "Quinzena": "Q2",
    "New_Product_Description": "Old Product",
    "Active_Ingredient": "Pimenta Vermelha",
    "Familia": "Pimenta",
    "Group": "Grupo do IA",
    "Linha": "Albaugh",
    "Devolução_Faturamento": "Faturamento",
    "Dia": 10,
    "mes": 1,
    "ano": 2015,
    "Concatenar": "",
    "Crop": "22 - CROP",
    "Version": "OPQ",
    "Tipo_Nota": "",
    "Data_Lancamento": "",
    "Data_Vencimento": "",
    "Prazo": "",
    "Condicao_Pagamento": "",
    "IGM": 1.0,
    "COGS": 2.0,
    "Net_Sales_VP": 1.000,
    "Net_Sales": 500,
    "Volume": 2,
    "ICMS_Tax": 100,
    "Freight": 100,
    "Interest": "-",
    "Receita_Invoice": 3.000,
    "Preco_Lista_Invoice_a_vista": "3,9",
    "Preco_a_prazo": "3,9",
    "Faturamento_Lista_Invoice": 10,
    "Net_Sales_Lista": 10,
    "Discount": "-2%",
    "Range_Capaing": "#N/D",
    "Range_Capaing_2": "#N/D",
    "Preco_Net_Lista_usd": "3,6",
    "IGM_Lista": 2.957,
    "Cambio_Dia": "2,571",
    "Faturamento_rs": "R$ 1.500",
    "Cambio_mes": "",
    "Faturamento_usd_Financeiro": ""
  }

I filter these data and insert a variable that is an array. So good, everything working.

What I have to do is create an array with some data from this jSON, like this:

/* Variáveis para gerenciar o filtro */
        var GraphOne = [];
        var GraphTwo = [];

        /* Variáveis para inserir no Highcharts */
        var HighchartsOne = [];
        var HighchartsTwo = [];

        $scope.filteredDados.forEach(function(arrayItem){

            if(arrayItem.Condicao_Pagamento != ''){
                GraphOne[arrayItem.Condicao_Pagamento] = GraphOne[arrayItem.Condicao_Pagamento] || [];
                GraphOne[arrayItem.Condicao_Pagamento].push(arrayItem.Net_Sales);
            }

            if(arrayItem.RTV != ''){
                GraphTwo[arrayItem.RTV] = GraphTwo[arrayItem.RTV] || [];
                GraphTwo[arrayItem.RTV].push({netsales:arrayItem.Net_Sales, igm: arrayItem.IGM, familia: arrayItem.Familia});
            }
        });

In the first block it creates an array and inserts the payment terms:

if(arrayItem.Condicao_Pagamento != ''){
                    GraphOne[arrayItem.Condicao_Pagamento] = GraphOne[arrayItem.Condicao_Pagamento] || [];
                    GraphOne[arrayItem.Condicao_Pagamento].push(arrayItem.Net_Sales);
                }

It inserts right. I do a console.log (GraphOne); and it returns me the right array. But in the second block that is the problem. I put console.log(GraphTwo); and it apparently on the console gives me the result:

  

Array []

And after a few seconds I click on this Array[ ] it informs me the data it has on it, which in this case is what I need. The strange thing is that when this Array[ ] appears and I click on it immediately nothing happens, but after a few seconds, if I click again, it shows me. The bad thing is I need to read this Array further in code, but I think the code thinks it's an empty array and does not read. The first block reads normally.

I do not know if it's because his index (GraphTwo [arrayItem.RTV]) is a name that contains spaces like Alisson Acioli , but I really do not know what it can be.
