Feature: trafficlights system

[willie68]

I would like to have a traffic light system on the bargraph. So that i can define some limit values like: green temp < 70°, yellow for 70-80° and red for values > 80°...

I "third" that! please let us have some kind of traffic lights, either by changing bargraph colour entirely or changing just above threshold.
