CanvasJS Chart Data not showing

Question

Got a question for you. I'm working with CanvasJS charts, and the chart is not showing data when rendering.

First i'm initialising the chart using this:

integrity.initChart = function() {
    var chart = new CanvasJS.Chart("integrityChart", {
        animationEnabled: true,
        animationDuration: 2000,
        title: {
            text: integrity.stockCode + " Integrity"
        },
        axisX: {
            title: "Date"
        },
        axisY: {
            title: "Value"
        },
        toolTip: {
            shared: true
        },
        legend: {
            cursor: "pointer",
            verticalAlign: "top",
            horizontalAlign: "center",
            dockInsidePlotArea: true,
            itemclick: toogleDataSeries
        },
        data: [
        {
            toolTipContent: "{x} - {y} (Stoploss: {stoploss}%)",
            type:"line",
            name: "Integrity minute",
            yValueFormatString: "###.##",
            showInLegend: true,
            markerSize: 0,
            dataPoints: [

            ]
        },
        {
            toolTipContent: "{x} - {y} (Stoploss: {stoploss}%)",
            type: "line",
            name: "Integrity hour",
            showInLegend: true,
            yValueFormatString: "###.##",
            markerSize: 0,
            dataPoints: [

            ]
        },
        {
            toolTipContent: "{x} - {y} (Stoploss: {stoploss}%)",
            type: "line",
            name: "Integrity day",
            showInLegend: true,
            yValueFormatString: "###.##",
            markerSize: 0,
            dataPoints: [

            ]
        }
    ]
    });

    integrity.chartObject = chart;
}

And i can see the chart, very nicely, but then i call the update data method.

integrity.renderChart = function() {
    $.ajax({
      url: integrity.requestBase + '&data=integrity',
      cache: false,
      dataType: "json",
      success:function(result) {
          var lowest = null;
          var highest = null;
          var i = 0;

            for (var key in result) {
                if (result.hasOwnProperty(key)) {
                    i = 0;
                    while (i < result[key].length) {
                        if (lowest == null) {
                            lowest = result[key][i].y;
                            highest = result[key][i].y;
                        }

                        if (lowest > result[key][i].y) {
                            lowest = result[key][i].y;
                        }

                        if (highest < result[key][i].y) {
                            highest = result[key][i].y;
                        }
                        i++;
                    }
                }
            }

          integrity.chartObject.options.axisY.viewportMinimum = lowest-(highest-lowest);
          integrity.chartObject.options.axisY.viewportMaximum = highest+(highest-lowest);
          integrity.chartObject.options.axisY.margin = 0;
          integrity.chartObject.options.data[0].dataPoints = result.minute;
          integrity.chartObject.options.data[1].dataPoints = result.hour;
          integrity.chartObject.options.data[2].dataPoints = result.day;
          integrity.chartObject.render();
      }
  });
}

And still no data is to be found, i did an alert(result.day.length) and it did show me ca 70 entries, so the data is getting set to the dataPoints well, but no joy.

Here's a sample of the data as well.
