         }
     },
     xAxis: {
         categories: mes, // What returns mes is ['Enero', 'Febrero', 'Marzo', 'Abril', 'Mayo', 'Junio', 'Julio', 'Agosto', 'Septiembre','Octubre', 'Noviembre', 'Diciembre'];
         crosshair: true,
         accessibility: {

         }
     },
     tooltip: {
         valueSuffix: ' (COP)'
     },
     plotOptions: {
         column: {
             pointPadding: 0.2,
             borderWidth: 0,
             dataLabels: {
                 enabled: true,
                 formatter: function() {
                     return '$' + Highcharts.numberFormat(this.y, 0);
                 }
             }
         }
     },
     series: [{
         name: 'Ventas',
         data: venta // What returns is ['1356940858.000000', '1945419126.000000', '934706589.000000', '1803607453.000000', '78415027.000000'] 
         // data: valoresY
     }],
     data: {
         table: 'datatable'
     },
     exporting: {
         tableCaption: "Tabla de Ventas Mensualesss"
     }
