Thank you for your help, but it isn't working. I've been playing around with everything I can think of, but I cannot get the graphs to display if I collect data in frequencies greater than 10 minutes. I was briefly looking through the code and I found in do_rrd.c that the default interval for RRD is 300 seconds (5 minuets). I cannot figure out a way to change this. The closest I have come to getting this to work was to add a heartbeat value to the NCV_ setting in xymonserver.cfg file to: NCV_mytest=dataset:GAUGE:1800. Then I was able to dump the XML using rrdtools, manually update the STEP to 900, and reload the rrd. When I do so, I get a strange behavior that makes me think the 300 value that is hardcoded overrides the changes I made. When the first report comes in, the rrd file is created, the second report grabs the correct data, then the third report the last_ds value is populated with the previously correct data and the current value is set to "NaN" and that is the way it stays for all subsequent tests.
Ultimately my RRD looks like:
<?xml version="1.0" encoding="utf-8"?> <!DOCTYPE rrd SYSTEM "http://oss.oetiker.ch/rrdtool/rrdtool.dtd"> <!-- Round Robin Database Dump --><rrd> <version> 0003 </version> <step> 900 </step> <!-- Seconds --> <lastupdate> 1356032234 </lastupdate> <!-- 2012-12-20 14:37:14 EST -->

man rrdtool. Or you can just redo what you did with to create the custom graphs, but just change the time interval.
Thanks, Larry Barber

The rrd databases are fixed length files, so you are leaving lots of blank entries between data points.

The script that collects the data was running every minute. After I finished testing, I changed the frequency of the scripts on the clients to 1 hour in the clientlaunch.cfg file. When I did, the RRD graph stopped displaying data. It ran like this for a couple days. I changed clientlaunch.cfg back to 1 minute... and the graphs immediately started graphing again. Is there a minimum time frame that is needed, or something else that must be done?
