[rrd-users] "Binary" graphs out of NagiosGraph

[Daniel MacKay]

Hello from a long long time Nagiosgraph user!

I have just moved a couple-year-old nagios + nagiosgraph setup from one i86 Solaris machine to another, upgrading everything in the process.  I got RRD 1.4.2 and Perl from Blastwave, and RRDTool from CPAN.

Now, ALL my graphs are all coming up as binary!  They're at zero during NaN times, and at just one value when there's any real data.  I can tell from a rrdtool dump, that the correct data is being stored, but the graphs are all square edged, like this:

(notice that it's displaying Cur= 63.32 but the line is not there.)

Below are the rrdgraph calls that created it.  

Can anyone help me figure out what is wrong with the calls? Then I can fix NagiosGraph.  Many thanks. -dan
