    var weightData = JSON.parse(weightForAgeJsonData);
    console.log(weightData);

    var chart = new CanvasJS.Chart(“chartContainer”, {
    animationEnabled: true,
    title:{
    text: “Cumulative App Downloads on iTunes and Play Store”
    },
    axisY :{
    yValueFormatString:”0.0″,

    includezero:false

    },
    axisX: {
    valueFormatString: “0”,
    title: “Months After Launch”,
    interval:5,
    includezero:false
    },
    toolTip: {
    shared: true
    },
    data: [
    {
    includezero:false,
    type: “stackedArea”,
    name: “Android”,
    markerType: “none”,
    showInLegend: true,
    dataPoints: ParseDatapoints(weightData[0])
    },
    {

    includezero:false,
    type: “stackedArea”,
    name: “Android”,
    markerType: “none”,
    showInLegend: true,
    dataPoints: ParseDatapoints(weightData[1])

    }
    ]
    });
    chart.render();

    }

    According to the values if we see using tooltip in fiddle y axis labels are not proper

    Kindly help me in this Its a POC so that later i can buy licence version of it

    below is my js fiddle

    @ahmedali123,

    Stacked Area Charts are Area Charts plotted together with aligned x values, such that at any point it shows a cumulative total of that point for all series. Because of this reason, the dataSeries will be shown at the value which is the sum of all its previous dataSeries.
