title: amCharts Stock Chart with multiple datasets not showing
body: <p>I went through the examples and docs of amCharts.</p>
  
  <p>Here is my problem: the chart is showing just a line and not two as defined in the 2 datasets:</p>
  
  <pre><code>var chart;
  
  function createStockChart() {
    chart = new AmCharts.AmStockChart();
  
  
    // DATASETS //////////////////////////////////////////
  
      var dataSet = new AmCharts.DataSet();
      chart.dataSets = [{
        title: "XWD.TO",
        color: "#000000",
        fieldMappings: [ {
        fromField: "value",
        toField: "value"
        }, {
        fromField: "volume",
        toField: "volume"
        } ],
        dataProvider: chartData,
        categoryField: "date"
      },
  
      {
        title: "portfolio-top-9-12-2015",
        color: "#FF0000",
        fieldMappings: [ {
        fromField: "value",
        toField: "value"
        }, {
        fromField: "volume",
        toField: "volume"
        } ],
        dataProvider: chartData2,
        categoryField: "date"
      }];
  
  
  
    // PANELS ///////////////////////////////////////////
    // first stock panel
    var stockPanel1 = new AmCharts.StockPanel();
    stockPanel1.showCategoryAxis = false;
    stockPanel1.title = "Price";
    stockPanel1.percentHeight = 70;
  
    // graph of first stock panel
    var graph1 = new AmCharts.StockGraph();
    graph1.valueField = "value";
    graph1.comparable = true;
    graph1.compareField = "value";
    graph1.type = "smoothedLine";
    graph1.bullet = "round";
    graph1.lineThickness = 2;
    graph1.bulletBorderColor = "#FFFFFF";
    graph1.bulletBorderAlpha = 1;
    graph1.bulletBorderThickness = 3;
    stockPanel1.addStockGraph(graph1);
  
  }
  </code></pre>
  
  <p>For full page code: 
  <a href="http://www.fanta-trade.eu/chart.php?tipo=a&amp;code=XWD.TO&amp;compare_top=1&amp;time=1449658858" rel="nofollow">http://www.fanta-trade.eu/chart.php?tipo=a&amp;code=XWD.TO&amp;compare_top=1&amp;time=1449658858</a></p>
  
  <p>It's like if the code is not fetching the second dataset.</p>
