Hi,
I wrote a test reporting voltages from my motherboard's sensors. Those values are positives and negatives (+12V, -12V). I use split NCV to get values in different RRD files, and almost everything is OK, but I don't have any value for the negatives voltages. I added a - before the numeric value, but I don't get any value in RRD file : user at host:~$ rrdtool dump ~xymon/data/rrd/host/hardware,Negative_12V_volt.rrd |head -50 <!-- Round Robin Database Dump --><rrd> <version> 0003 </version> <step> 300 </step> <!-- Seconds --> <lastupdate> 1232991020 </lastupdate> <!-- 2009-01-26 18:30:20 CET -->

Make them positive and put them the rrd. If you createt the graph, you can make them negative again.

(I think that's the syntax).
Right now your minimum is set to zero.

The fix in Hobbit to always permit negative values has been added for both the current development version, and the 4.2.3 update.
