title: Dynamically update gauge on highcharts
body: <p>I'm working in a university website project, and I choose to work with Highcharts, it has a very easy usage. But i'm having some problems to work with <code>.getjson</code> for dynamically update.</p>
  
  <p>I used this <a href="http://www.highcharts.com/studies/live-server.htm" rel="nofollow noreferrer">http://www.highcharts.com/studies/live-server.htm</a>, and this <a href="http://jsfiddle.net/oceog/zpwdp/" rel="nofollow noreferrer">http://jsfiddle.net/oceog/zpwdp/</a> samples.
  And I havenn't got any success. Then i try to learn by my own on the API, and i came to this:</p>
  
  <pre><code>function requestData() {
      $.jQuery.getJSON('values.php', data, 
          function(){
              var series = chart.series[0]
              chart.series.update()
              setTimeout(requestData, 1000);  
          }
  )}
  </code></pre>
  
  <p>I left the data values on the chart empty, and i loaded <code>requestData</code> on the file, but it still don't work.
  Can someone help me?
  Sorry for my english.
  Thanks!</p>
