title: Chart refresh avoiding dashboard refresh in pentaho CDE
body: <p>I'm developing a 3 charts dashboard, with pentaho cde (from community ctools).</p>
  
  <p>The 3 charts are displayed one below the other, so they're not visible to the user unless scroll.</p>
  
  <p>My current problem is that when I want to navigate through the charts in the lower part of the dashboard (for which I have to scroll down first), the events I create make all my dashboard refresh, and therefore I loose my previous scroll down, so I have to scroll down again, or force it grammatically.</p>
  
  <p>Tests lead me into  the thinking that the problem may be the way I create the events.</p>
  
  <p>I've tried</p>
  
  <pre><code>Dashboards.fireChange('parameter',variable);
  </code></pre>
  
  <p>or</p>
  
  <pre><code> Dashboards.update(Dashboards.getComponent('myChart'));
  </code></pre>
  
  <p>But no success, both make a kinda scrollTop.</p>
  
  <p>Is there any way to 'navigate' through a chart, and not loosing the scroll?</p>
  
  <p>'Navigate' means to use a chart to show multiple hierarchies, all in the same chart, so as family > subfamily > article, using the clickable / click action options.</p>
  
  <p>Hope you can help me, 
  thx in advance.</p>
