Element-specific attributes #

value = float

The “measured” value shown by meter.

min = float

low = float

The point that marks the upper boundary of the “low” segment of the meter.

high = float

The point that marks the lower boundary of the “high” segment of the meter.

max = float

The upper bound of the range for the meter.

optimum = float

The point that marks the “optimum” position for the meter.
