title: How to get the series of points that are generated with "click to add" in highcharts?
body: <p>You can ask the user to supply data by clicking to adding points to a char, see <a href="http://www.highcharts.com/demo/dynamic-click-to-add" rel="nofollow">this demo</a>.
  But I don't know how to retrieve those points and send them back to the server (with a POST or AJAX, whatever). I just want to know how to get them in javascript.</p>
