custom graphs

[dOCtoR MADneSs <doctor (at) makelofine.org>]

Hi,

I created some tests, and I get graphs from them, using splitncv
All is almost perfect (I get values, they are stored in separate files, 
the graphs are made), but I have a little issue.
In trends page, I get my custom graphs, then 2 useless lines (having the 
name of my custom graphs). I attache a screenshot that is better 
descritption.
I'd like to remove those useless lines, that's all. I tried to 
add/remove/modify GRAPHS section in hobbitserver.cfg, TRENDS definition 
in bb-hosts, without any result (I can't  get more or less useless lines).

Any help is very welcome.
