Update of /var/lib/cvs/congo/monitor
In directory boomer:/tmp/cvs-serv6380/monitor

Added Files:
Chart.java MainFrame.java Monitor.java
Log Message:
The first vestiges of a Java Swing based monitoring program that will
run in realtime, showing registration activity over a series of
specified time intervals. It also shows live counts of subscribed,
registered, badged, and checked-in attendees.

Initial coding and layout is done, XMLRPC hooks are in and sample calls
are working. I've included JFreeChart in the package to allow on the fly
graph generation.

Sample of what it looks like:
http://www.homeport.org/~dbs/screenshots/monitor-6.png (obviously the
graph data is not from CONGO - but it is generated on the fly by
JFreeChart.)
