graph positive and negative values

Hi, I'm wondering if anyone has been successful setting up and graphing an
item that fluctuates between positive and negative values?  I'm trying to
trend the temperature of my freezer.  When I created the rrd earlier today
(when positive values were generated) the graph was functional.  When I put
my sensors inside the freezer (where the temperatures drop a few degrees
below zero F) the values wouldn't drop below zero on the graph.
I tried modifying the current rrd tool with:
rrdtool tune /home/hobbit/data/rrd/tice/freezer.rrd --minimum freezerf:U
(which did drop the minimum to nan) but I still couldn't get negatives to
show on the graph.  I thought I'd delete the rrd and start over - but I
think now that the values are negative numbers the rrd won't even create.
 Here is a snippet from my hobbitgraph and hobbitserver files

If anyone has an idea please let me know - I'd really like to trend this

Is there any way to get the sensors to output in Kelvin?

Hi,

there's a small bug in hobbitd_rrd 4.2.0 which prevents negative values to
be plotted. You have to upgrade to a snapshot or backport a few
modifications from do_ncv.c : the "l = val + strspn(val, "0123456789.")"
part and the creation arguments of the rrd file.

Thanks Ben, I can configure the script to convert the temperature into
Kelvin's - I think I'll do that if I can't get a hold of a current snapshot.

Thanks for the info Charles.  A question you (or anyone really) might be
able to answer.  Where do I get the snapshot from?  I thought it would be
hosted on sourceforge - but when I went here (
http://hobbitmon.cvs.sourceforge.net/hobbitmon/ ) to look at the cvs
repository it only has the hobbitc.  Can someone point me in the right
direction please?


Thanks!

Look for a thread at 19 Feb 2007 named "ncv can't handle negative
values", there's some easy fixes for your case:

    Hi,

    there's a small bug in hobbitd_rrd 4.2.0 which prevents negative
    values to
    be plotted. You have to upgrade to a snapshot or backport a few
    modifications from do_ncv.c : the "l = val + strspn(val,
    "0123456789.")"
    part and the creation arguments of the rrd file.


Thanks for the info Charles.  A question you (or anyone really) might be able to answer.  Where do I get the snapshot from?  I thought it would be hosted on sourceforge - but when I went here ( http://hobbitmon.cvs.sourceforge.net/hobbitmon/ ) to look at the cvs repository it only has the hobbitc.  Can someone point me in the right direction please?

Snapshots are here:  http://www.hswn.dk/beta/

The link to it is from the http://www.hobbitmon.com page.
