title: Highcharts legend events without displaying a legend
body: <p>Is it possible to trigger this event which is triggered when we click on a Highcharts legend element (this one who hide or show a chart element), with Highcharts legend disabled ?</p>
  
  <p>And in general, how can we do what we want to do with Highcharts event, bypassing the Hightcharts system (which is like anOption : { anOtherOption : aValue, .... ) ?</p>
