Class FlotRenderer

java.lang.Object
  org.apache.commons.monitoring.reporting.AbstractRenderer
      org.apache.commons.monitoring.reporting.FlotRenderer

All Implemented Interfaces:

Renderer

public class FlotRenderer
extends AbstractRenderer

Render as a graph, based on jQuery Flot javascript library

This renderer produces JavaScript, and expect the HTML page to include

• the required <script> tags :

     <script src="jquery.pack.js" ></script>
     <script src="jquery.flot.pack.js" ></script>
     <!--[if IE]><script src="excanvas.pack.js" ></script><![endif]-->
   

• a <div& id="placeholder"gt; to draw the graph into, having width and height style set.
