By default the <EXTRA_DATA TITLE> is the same as the metric name.  However if 
you add a Title="blah" to any Metric{} block in gmond.conf file, that title is 
reflected in the <EXTRA_DATA TITLE> tag.  This way the user is able to name 
their own graphs and constant metrics anything they want (provided the web 
frontend is refactored to use the TITLE rather than the NAME attribute).  You 
aren't seeing any difference now because I haven't added any titles to the 
gmond.conf file.  But all of the functionality is there and works.  The web 
frontend just  needs to support it.
