Find the highest value within the specified intervals.
Defines the time series data fed into the function. This can be a sensor ID or another function.
Number of data intervals considered in the function
*Input data is optional in most cases. If Info360 detects that the first input is time series data, it will be applied to the function. Otherwise, the current active sensor's data will be used, which is often the case in Reference Charts.
Example Usage as an Expression:
Highest(PercentFull(),10) - Finds the highest percent full values in the last 10 intervals.
Highest(High(), 10) - finds the highest values in the last 10 intervals (including data points measured in between the sampled interval).
Highest(Change(1), 10) - finds the highest values changed in the last 10 intervals.
Example Reference Chart:
The following chart is a simple example of using the Highest function to track the highest pressure over the previous 48 hours. Notice that at the beginning of the period, Highest is equal to the first value, but as spikes occur it tracks the highest spike over the past 48 hours. After 48 hours has passed since the highest value, the results drop down to the next highest value.
