title: Dynamic Highcharts with maximum xaxis points
body: <p>I try to create dynamic highcharts. I use <code>series.addPoint</code>. It works fine but my chart adds points and doesn't move like here - <a href="http://jsfiddle.net/gh/get/jquery/1.9.1/highslide-software/highcharts.com/tree/master/samples/highcharts/demo/dynamic-update/" rel="nofollow">jsfiddle</a>. It can be with 100 points on the screen.
  How can I make only 10 points on the screen and hide old points? </p>
