I've seen this before but I don't remember the exact cause, I just remember that working on rrd stuff tended to add gray hair. Do both of these graphs have essentially the same rrd configs? If the foo.rrd files do not contain the detail for the tests I would truncate foo.rrd, and recheck my [foo] graph stanza. (rather, save a copy off foo.rrd first)

accidentally snipped off the tail interval there, but it's still matching:

You can see that the first test has chunks missing at regular
intervals. These two graphs were made from the same data, sent from
the same perl script, to two different tests, RTM and rtmstats. I did
this originally back when I was having trouble with RRD choking on the
extra information and wanted to separate the stats, but I've kept it
because the one graph is so spotty. On the client side,my perl script
for the test is logging that it is sending the data correctly, and I
believe it's always displaying correctly on the test page
On the xymon server, I see the rrd file for RTM is missing some
entries that are populated on the rtmstats, for example:
RTM:
<!-- 2012-08-01 17:05:00 EDT / 1343855100 -->
<row><v>3.5954352000e+05</v><v>3.5456424000e+05</v><v>1.0610000000e+03</v><v>3.9142800000e+03</v><v>4.9752800000e+03</v><v>1.3876000000e+00</v></row>
<!-- 2012-08-01 17:10:00 EDT / 1343855400 -->
<row><v>NaN</v><v>NaN</v><v>NaN</v><v>NaN</v><v>NaN</v><v>NaN</v></row>
rtmstats:
<!-- 2012-08-01 17:05:00 EDT / 1343855100 -->
<row><v>3.5954352000e+05</v><v>3.5456424000e+05</v><v>1.0610000000e+03</v><v>3.9142800000e+03</v><v>4.9752800000e+03</v><v>1.3876000000e+00</v></row>
<!-- 2012-08-01 17:10:00 EDT / 1343855400 -->
<row><v>3.8017446000e+05</v><v>3.7497760000e+05</v><v>1.0860800000e+03</v><v>4.1067800000e+03</v><v>5.1928600000e+03</v><v>1.3678000000e+00</v></row>
What could be causing this discrepancy?
Looking at that interval on the client side log:
