title: Kibana multi graph
body: <p>I am currently using kibana3 and elasticsearch to monitor my system and I'm having trouble to create 3 line charts on the same graph.</p>
  
  <p>Example :</p>
  
  <p>I have the following line :</p>
  
  <pre><code>    {
  "@version":"1","@timestamp":"2015-02-03T10:06:35.539Z","host":"localhost","plugin":"load","collectd_type":"load","shortterm":0.4,"midterm":0.36,"longterm":0.33
      }
  </code></pre>
  
  <p>On kibana, I can just graph one of these : shortterm, midterm, longterm</p>
  
  <p>I would like to have the 3 of them on the same graph ..</p>
  
  <p>Thx for the help cheers!</p>
