title: Highcharts: trying to update series
body: <p>I'm trying to update Highchart series by clicking the button. For unknown reason the series can't be updated. Can someone help me, please? </p>
  
  <p>Here's a jsfiddle link: <a href="http://jsfiddle.net/cSx5c/1/" rel="nofollow">http://jsfiddle.net/cSx5c/1/</a></p>
  
  <p>See my code below:</p>
  
  <pre><code> chart: new Highcharts.Chart({
      chart: {
          renderTo:'container',
          type: 'bar',
          backgroundColor: 'transparent',
          height:200
      },
      tooltip: {
          positioner: function () {
              return {x:0,y:0}
          },
          formatter: function() {
              return '&lt;b&gt;' + this.series.name + '&lt;/b&gt;: &lt;b&gt;' + this.y + ' uur&lt;/b&gt;';},
          shadow: false,
          borderWidth: 0,
          backgroundColor: 'rgba(0,0,0,0.1)'
      },
      credits: {
          enabled: false
      },
      title: {
          text: 'Shift Overview'
      },
      xAxis: {
          lineWidth: 0,
          minorGridLineWidth: 0,
          lineColor: 'transparent',
          minorTickLength: 0,
          tickLength: 0,
          labels: {
              enabled: false
          },
          height: 50
      },
      yAxis: {
          categories: ['7:00', '8:00', '9:00', '10:00', '11:00', '12:00', '13:00', '14:00', '15:00', '16:00', '17:00', '18:00', '19:00'],
          tickmarkPlacement: 'on',
          height: 50
      },
      legend: {
          reversed: false
      },
      plotOptions: {
          series: {
              stacking: 'normal'
          }
      },
      series: [{"name": "Production", "data": [3.5], "color":"green"}, {"name": "Changeover", "data": [1.5], "color":"lightblue"}, {"name": "Technical Failure", "data": [5], "color":"red"}, {"name": "Production", "data": [2], "color":"green"}]
  });
  </code></pre>
  
  <p>Here's the script for the button for adding new series:</p>
  
  <pre><code>$('#button').click(function() {
      var chart = $('#container').highcharts();
      var new_serie = [{"name": "Production", "data": [3.5], "color":"green"}, {"name": "Changeover","data": [3.5], "color":"lightblue"}, {"name": "Technical Failure", "data": [5], "color":"red"}];
      //alert(new_serie);
      chart.series[0].update({series: new_serie}, true);
  });
  </code></pre>
