You don't have to plot all data from an RRD in the same graph. E.g. the
"vmstat.rrd" files collect tons of data (around 20, if memory serves me right),
but there are several different graph-definitions that use this rrd-file to
display only a few of them.

You can only do this on the "trends" page; if you have a custom status column,
those status pages will only know how to show a single graph.

On the "trends" status, say you have a "mydata1", "mydata2" and "mydata3"
graphs defined in the hobbit-graphs.cfg file. Then you can put a
   TRENDS=*,mydata;mydata1|mydata2|mydata3
on the host definitions in bb-hosts, and the trends page will show those
three graphs one after the other. Note: The "GRAPHS" setting in hobbitserver.cfg
must have "mydata" listed as the graph, not "mydata1" (or 2 or 3).
