title: Live monitoring charts on a web page
body: <p>I want to make my web page live or interactive like having monitoring or analysis kind of thing, on refreshing data periodically..</p>
  
  <p>For example, google's <a href="http://code.google.com/webtoolkit/speedtracer/get-started.html" rel="nofollow">speedtracer</a>..</p>
  
  <p>There are many api's like <a href="http://www.jfree.org/jfreechart/" rel="nofollow">jFreeChart</a> to draw a static chart, but i want it like to refresh periodically, there is an option to perform it by polling but that would effect the look of the site and also it gets time consuming operation to get effect reflected to user.</p>
  
  <p>Is it possible to do on a web page using javascript or jQuery or any api's available?</p>
  
  <p>Thanks..</p>
