delete the oldest points from the chart

[Lauren Michelle Mendoza]

I'm trying to do something like this:

http://jsfiddle.net/gh/get/jquery/1.7.2/highslide-software/highcharts.com/tree/master/samples/highcharts/members/series-addpoint-append-and-shift/

I'm able to add points but not sure how to delete the old ones.

thanks

You should be able to just remove the point from the array and the chart will update.
