How to use Qlik data in extensions?

[Anonymous]

Hi,

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 = new Array(2);

        }

  //Getting the data from QlikView

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

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

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

            row[1] = Number(temp);

        }

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

  alert("hello");

  /*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.
