Hi Tobi,

unfortunatly i can't easily stop the logging of the bad data to the RRD (in 
fact it will probably be quicker to modify the scripts to calculate the 
correct data rather than no data - the long-term fix that i will refer to in 
my first post). Is it possible to set a NaN with cdef though? Alex vd B has 
suggested using TREND, but so far i can;t get that to smooth out quite how 
I'd like either.
