无法在QlikView的

Question

我使用下面的谷歌图的扩展性和代码来查看图表在谷歌饼图扩展如下：

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

    function loadGoogleCoreChart() { 
google.load('visualization', '1', { 
    packages: ['corechart'], 
    callback: googleCoreChartLoaded 
}); 
} 

function googleCoreChartLoaded() { 
Qva.AddExtension('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); 
    } 

    //Changing the array to a data table 
    var data = google.visualization.arrayToDataTable(row); 

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

我已经使用脚本编辑器，选择加载的样本数据后在扩展中的维度我无法看到图表。任何人都可以帮助我什么是错的？

这是工作的功能：

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() { 

    var html = "<script type=\"text/javascript\" src=\"https://www.gstatic.com/charts/loader.js\"></script>"; 
    html += "<div id=\"piechart\" style=\"width: 900px; height: 500px;\"></div>"; 

    this.Element.innerHTML = html; 
    this.Element.innerHTML = "<h1>Testing Extension</h1>"; 

    var data = google.visualization.arrayToDataTable([ 
     ['Task', 'Hours per Day'], 
     ['Work',  11], 
     ['Eat',  2], 
     ['Commute', 2], 
     ['Watch TV', 2], 
     ['Sleep', 7] 
    ]); 

    var options = { 
     title: 'My Daily Activities' 
    }; 
    new google.visualization.PieChart(this.Element).draw(data, { chartArea: { left: 20, top: 20, width: "100%", height: "100%"} }); 
}); 
} 

虽然，在这里我有存在于功能本身的数据。我仍然需要弄清楚如何接受Qlikview的投入，我敦促任何知道这个技巧的人帮助我。
