title: Highstock get detailed info when data is grouped
body: <p>In the click event "this.x" is the first point in the data group.</p>
  
  <p>dataGrouping occurs when you play with the scroll, for example if select show all data, each point represent a week but you have information about every day, so in this point is represented info of all week instead of each day.</p>
  
  <p>¿how I can get the last point in the data group clicked? ¿Hoy can I get the last point represented in this group (in this week)? (week is an example when you play with the scroll grouped data can happen in non common intervals)</p>
  
  <pre><code>            plotOptions : {
                  series : {
                      point : {
                          events : {
                              click : function(event) {
                                  alert(this.x + '  ' + this.y);
                                  //HERE?
                              }
                          }
                      }
                  }
              },
  </code></pre>
