Outputs the highest value within a given sampling interval.
For example, if an hourly sampling interval is applied to a chart, High() will give the maximum raw data point reported over the previous hour.
Specifically, the High() reported value at 2:00, is the maximum of every raw sensor value reported between 1:01 and 2:00.
The unique ID of the sensor data to be used in the function.
High('PRV1-2B.PRV Flow Rate'): Returns the high values for sensor PRV1-2B. PRV Flow Rate over each sampling interval.
The following example shows various reports of daily tank levels overlaid on an Candlestick Chart. The Open and Close value indicate whether the tank experienced a net filling or draining through the day, while High and Low show the range of values that day. The Average value shows the central tendency.
