title: Highcharts: Area clickable
body: <p>I have an area Highchart chart.
  Added a click event to the chart, like this:</p>
  
  <pre><code>plotOptions: {
                  area: {
                      marker: {
                          enabled: false
                      },
                      cursor: 'Pointer',
                      stacking: 'normal',
                      events: {
                          click: function(event) {
                            alert("hi there");
                          }
                      }                   
                  }
              }
  </code></pre>
  
  <p>It works fine. The problem is that you can only click very near to a line, but not on the area below the line, it is not clickable.</p>
  
  <p>Is there a setting that I overlooked?</p>
