Cricket/rrdtool will happily graph negative numbers. You didn't happen
to specify your rrd-min as 0 did you? You can use 'rrdtool info
/path/to/file.rrd' to see if that's the case. In the snippet below, ds0
has a minimum value of 0 and an unlimited max value--


ds[ds0].type = "GAUGE"
ds[ds0].minimal_heartbeat = 1800
ds[ds0].min = 0.0000000000e+00
ds[ds0].max = NaN
ds[ds0].last_ds = "UNKN"
ds[ds0].value = 6.4000000000e+01
ds[ds0].unknown_sec = 0
