I have setup a sensor with 4 channels, 2 of which should show an error if offline. The other 2 should not be an error if they are offline. I am using prtg.standardlookups.connectionstate.stateonlineok and prtg.standardlookups.connectionstate.bothok.
The guage for prtg.standardlookups.connectionstate.stateonlineok points to the right for a value of 1 (and left for a value of 0).
The guage for prtg.standardlookups.connectionstate.bothok points to the left for a value of 1.
This is state depending and always goes clockwise. Green at the start, red at the beginning. All values resembling the same state will appear in order of appearance in the lookup.
