title: Polar Chart displaying as line chart?
body: <p>I am trying to create polar spider chart but it is displaying it as line graph.
  I am doing it via making ajax calls.I have set these properties.</p>
  
  <pre><code>              chart=new {
  
                      polar = true,
                      type = "line"
                  },
                  title = new
                  {
                      text = project
                  },
                  xAxis = new
                  {
                      categories = pivotvalues,
                      tickmarkPlacement = "on",
                      lineWidth = 0
                  },
                  yAxis = new
                  {
                      gridLineInterpolation = "polygon",
                      lineWidth = 0,
                      min =0
                  },
  </code></pre>
  
  <p>I am populating the data for series from my database. It is showing as a line graph instead of polar-spider. Any suggestions?
  I am loading the scripts in following order as well.</p>
  
  <pre><code>&lt;script src="http://code.highcharts.com/highcharts.js"&gt;&lt;/script&gt;
  &lt;script src="http://code.highcharts.com/highcharts-more.js"&gt;&lt;/script&gt;
  &lt;script src="http://code.highcharts.com/modules/exporting.js"&gt;&lt;/script&gt;
  </code></pre>
  
  <p>Any suggestion where i might be doing it wrong? </p>
