    How to use Qlik data in extensions?

    Ashesh Das


      I followed the code mentioned in the following link of the community:


      Anyone know how to use Google Charts (not Maps) in an extension?


      I downloaded the file which was uploaded by mikecarpenter as I wanted to make an extension using the Google Pie Chart. However I am unable to take the input from Qlik when I use this code. On the contrary whenever I enter some data within the JavaScript itself the chart gets rendered. Can anyone please help me with this issue as I am unable to understand where I am going wrong. I am attaching the code here and I have commented out the lines where I have manually entered the data.

      Please find the code below:


      Qva.LoadScript("http://www.google.com/jsapi?callback=loadGoogleCoreChart", function () {




      function loadGoogleCoreChart() {

          google.load('visualization', '1', {

              packages: ['corechart'],

              callback: googleCoreChartLoaded





      function googleCoreChartLoaded() {


        Qva.AddExtension('QlikView/Examples/GooglePieChart', function () {


        //Declaring a two dimensional array (an array of arrays)

        var row = new Array(this.Data.Rows.length + 1);

              for (var i = 0; i <= this.Data.Rows.length; i++) {

                  row[i] = new Array(2);


        //Getting the data from QlikView

        for (var j = 1; j <= this.Data.Rows.length; j++) {

                  row[j][0] = this.Data.Rows[j - 1][0].text;



                  var temp = this.Data.Rows[j - 1][1].text;

                  row[j][1] = Number(temp);



        var data = google.visualization.arrayToDataTable(row);



        /*var data = google.visualization.arrayToDataTable([

                ['Task', 'Hours per Day'],

                ['Work',     11],

                ['Eat',      2],

                ['Commute',  2],

                ['Watch TV', 2],

                ['Sleep',    7]




        new google.visualization.PieChart(this.Element).draw(data, { chartArea: { left: 20, top: 20, width: "100%", height: "100%"} });




      Please help me out, it is urgent.
