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.
