body: <p>Im referring square crossfilter plugin for javascript</p>
  
  <p><a href="https://github.com/square/crossfilter" rel="nofollow">https://github.com/square/crossfilter</a></p>
  
  <p>In my app, users are be able to select specific date ranges and each time the date is changed, an ajax request creates a json object which is fed into crossfilter.</p>
  
  <p>I want to be able to remove the existing crossfilter (objects on screen as well as events) and start a new with the  newly created json object.</p>
