Calculate the lowest value among a set of sampled values.
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:
Lowest(PercentFull(),10) - Finds the lowest percent full values in the last 10 intervals.
Lowest(Low(), 10) - finds the lowest values in the last 10 intervals.
Lowest(Change(1), 10) - finds the lowest values changed in the last 10 intervals.
Examples Reference Chart:
The following example tracks the lowest recorded Minimum Nightly Flow over time. Tracking this value is often used as an estimate of leakage in a system. In this case, Lowest(90) will report the lowest value over the past 90 days.
