I don't know without RRD but with using rrdtool I graphs negative data fine, just do something like "rrdtool tune targetfile.rrd -i ds0:-50"

I have a mrtg script with is getting data from our Cisco DWDM metro switches. I am interested in the optical power health.(I have got the OID) In the mrtg graph i am not getting any values. When i try to get the OID with GETIF i got a value back that is below 0 (nullobj). How do I tell mrtg that the value it is getting is a negative value. Thnx, Ben van de Graaff.
