title: Kibana and fixed time spans
body: <p>Is it possible to set a fixed timespan for a saved visualization or a saved search in Kibana 4? </p>
  
  <p>Scenario:
  I want to create one dashboard with 2 visualizations with different time spans.</p>
  
  <ol>
  <li>A metric counting unique users within 10 min (last 10 minutes)</li>
  <li>A metric counting todays unique users (from 00.00am until now)</li>
  </ol>
  
  <p>Note that changing the time span on the dashboard does not affect the visualizations. Possible?</p>
