[hobbit] No graph from RRD data

[J.Rutten at rad.umcn.nl]

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?
