title: Highcharts - remove points from series
body: <p>Is it possible to remove certain points from a series?
  I'm looking for some way to draw a chart with a fixed back period,
  something like: the last 1 hour.</p>
  
  <p>I know how to add points using dynamic update:</p>
  
  <p><a href="http://www.highcharts.com/demo/dynamic-update" rel="nofollow">http://www.highcharts.com/demo/dynamic-update</a></p>
  
  <p>But in my case the time interval between points is not constant,
  so I can't just use the shift option of <a href="http://api.highcharts.com/highcharts#Series.addPoint%28%29" rel="nofollow">addPoint</a>.</p>
  
  <p>Thanks,
  Omer</p>
