The next edition is going to have a lot on using rrdcached, so I can add this as well.

I want to know whether someone has a best practice for storing and displaying negative temperature values?
I know that MRTG and RRD do not store negative values. But maybe it is possible to add a constant value (lets say: +100) to the gathered values in the extended script, and let routers2.cgi know that it should interpret them as values with -100. For example: a temperature of 20 °C is stored as 120, while a temperature of -10 °C is stored as 90.

However, I am just interested if someone has ever made something like this, or if I should try to find some other software that fits my aims.

Here is an example of my daily temperature graph. Last night, the temperature was under 0 °C.
