  <p><a href="http://www.dhtmlx.com/docs/products/dhtmlxGantt/index.shtml" rel="nofollow">http://www.dhtmlx.com/docs/products/dhtmlxGantt/index.shtml</a></p>
  
  <p>I tried the sample of dhtmlxGantt in</p>
  
  <p><a href="http://www.dhtmlx.com/docs/products/dhtmlxGantt/download/dhtmlxGantt.zip" rel="nofollow">http://www.dhtmlx.com/docs/products/dhtmlxGantt/download/dhtmlxGantt.zip</a></p>
