Ok, I misunderstood that you had the GPS downstairs as well.

Glad you found the MRTG stuff of use.  You could probably use RRDtool to 
better effect to handle the bipolar values.  There was a suggestion to 
plot the positive and negative values separately, which I think you have 
used, but personally I don't like the results for normal viewing:

although they can be useful in that they auto-scale and allow you to see 
transients which would otherwise be off the normal graphs:

Had some "interesting" rain and thunderstorms this afternoon, and rebooted 
one PC, which is why there are some unusual transients showing.

Cheers,
