Just for safety, we should add a plus "+" and a comma "," to the string, in case some source of data provides +9,876.54 as a value.

is there an easy way to change the code so that ncv values can handle 
negative values.
I think there is: In the hobbit-4.2.0/hobbitd/rrd/do_ncv.c file around
line 65 there's this line:
     l = val + strspn(val, "0123456789.");
Add a "-" before the numbers so it becomes
     l = val + strspn(val, "-0123456789.");
Run "make" and copy the hobbit-4.2.0/hobbitd/hobbitd_rrd binary to your
~hobbit/server/bin/ directory (or just run "make install"), then restart
Hobbit.

Haven't tested it, but I think it should do the trick.
