I created a custom mysql parameters check that shows graphs on one

This is an error from the rrdtool library. So I would suspect something 
dodgy with the graph-definition in hobbit-graphs.cfg, or the RRD file 
data is not as you would expect.

Could you show us the graph definition you use ? And the layout of the 
RRD-file - a command like

	rrdtool info mysql.rrd |grep "type ="

should give us the necessary info about the datasets and their type.
If I request the same image for different server, same service - I get
the image. If I copy the mysql.rrd file from the
/var/lib/hobbit/rrd/atl-db01/mysql.rrd into the
/var/lib/hobbit/rrd/pa04, then the image for pa04 shows graph for the
atl-db01.

Could be that dash in name of that particular server was affecting the
hobbitgraph.cgi somehow? I can attach the hobbitgraph.d/mysql.cfg and
hobbitserver.d/mysql.cfg if that would help.
It shouldn't, and I know I have hostnames with dash'es in them. Haven't 
noticed any problems with graphs there, but I'll have a look.
