title: Highcharts scrollbar not appearing
body: <p>For some reason, the scrollbar option for Highcharts is not working on my Rails 3.2.1 application. What is odd is that everything looks exactly the same as this: <a href="http://jsfiddle.net/highcharts/fj6d2/" rel="nofollow">http://jsfiddle.net/highcharts/fj6d2/</a></p>
  
  <p>... except that the scrollbar is missing. I have the exact same code as that shown in the jsfiddle above, the graph appears on my local application, but the scrollbar is missing.</p>
  
  <p>This is the code in my local app, the same as in the jsfiddle:</p>
  
  <pre><code>var chart = new Highcharts.Chart({
  
  chart: {
      renderTo: 'container'
  },
  
  xAxis: {
      categories: ['Jan', 'Feb', 'Mar', 'Apr', 'May', 'Jun', 'Jul', 'Aug', 'Sep', 'Oct', 'Nov', 'Dec'],
      min: 6
  },
  
  legend: {
      verticalAlign: 'top',
      y: 100,
      align: 'right'
  },
  
  scrollbar: {
      enabled: true
  },
  
  series: [{
      data: [29.9, 71.5, 106.4, 129.2, 144.0, 176.0, 135.6, 148.5, 216.4, 194.1, 95.6, 54.4]
  }]
  });
  </code></pre>
  
  <p>Again, the graph shows, but only the scrollbar doesn't. Why isn't the scrollbar showing? Has anybody had success using a scrollbar in their highcharts graphs? I would love to get a fix for this, I really am stumped as to why its not working.</p>
