title: Highcharts JS showing wrong colors
body: <p>I'm trying to create a heatmap with values from -2 to 10. </p>
  
  <p>I want: </p>
  
  <p>-2 to be red
  0 to be white
  10 to be green</p>
  
  <p>I tried this <a href="http://jsfiddle.net/m5xfx0wa/1/" rel="nofollow">http://jsfiddle.net/m5xfx0wa/1/</a> but seems to not be working.</p>
  
  <pre><code>colorAxis: {
  
              stops: [
                  [-2, '#ff0000'],
                  [0, '#ffffff'],
                  [10, '#00ff00']
              ],
              min: -2,
              max: 10
          },
  </code></pre>
  
  <p>Any ideas?</p>
