#None

#Temp - automatic scaling for min/max

#Pressure - scaling with a pseudo-fixed scale which means the min/max values of the scale are set to the min/max all time records found in ''alltime.ini''. Highcharts itself sets the scale values such that there is a tick at the end of the scale and the min/max values fall between the ticks at the end of the scale. If the pressure gets a lower/higher value the axis will adjust automatically. The idea is that any barometer you have at home has a fixed scale and with small variations there is little movement of the needle. However when the pressure starts falling/rising significantly it is very obvious. This behaviour is mimicked by CUtils (as far as possible)

#Rain - automatic scaling with minimum value of 0 and an initial maximum of 1 (to accommodate measurement in inches)

#Rrate - automatic scaling with minimum value of 0 and an initial maximum of 1 (to accommodate measurement in inches)  

#Wind - automatic scaling for min/max  

#Direction - scaling is fixed for 0 to 360 degree. When only direction is plotted two axis are created: in degrees and in wind directions (N, E, S, W). When combined with another unit only the axis with wind directions is used.

#Humidity - scaling is fixed between 0 and 100

#Solar - scaling is fixed between 0 and a rough estimate of the maximum theoretical value for radiation + 150. If the actual value goes beyond that, the scale will adjust.

#UV - automatic scaling for maximum, minimum is 0

#Hours - automatic scaling for maximum, minimum is 0

#Distance - automatic scaling for maximum, minimum is 0

#DegreeDays - automatic scaling for maximum, minimum is 0

#EVT - automatic scaling for maximum, minimum is 0

#Free - has no title, unit or context associated with it. It just displays values. Automatic scaling for min/max.

#AQ - automatic scaling for maximum, minimum is 0

#ppm - automatic scaling for maximum which starts at 500, minimum is 0. The default maximum is because the CO₂ value is around 420 (in 2022) outdoors.
