[hobbit] No graph from RRD data

[Jones, Jason (Altrincham)]

" No graph on the status page, but OK on the trends page

Make sure you have ncv listed in the GRAPHS setting in hobbitserver.cfg.
(Don't ask why - just take my word that it must be there)."
?

Great!
Now the rrd file has the right type and the data shows up in the graph,
but graph is showed on the trends page only.

My hobbitserver.cfg:
TEST2RRD="cpu=la,disk,...,usage=ncv"
NCV_usage="usage:GAUGE"
GRAPHS="la,disk,...,usage"

How can I get the graph on the status page from the "usage" test?
