Outputs the final value within a given sampling interval.

For example, if a sensor gives raw data every 5 minutes, but an hourly sampling interval is applied to a chart, Close() will output the last raw data point within the past hour.

Specifically, the Close() reported value at 2:00, is the value reported at 2:00 (neglecting anything other raw data occurring during the hour).

Parameter

Description

Sensor ID

The unique ID of the sensor data to be used in the function.

Warning:

This function must be run directly on raw sensor data. An internal function cannot be used (e.g. High(Previous(4))), as this does not pass all the required information.

Example Usage as an Expression:

Close('PRV1-2B.PRV Flow Rate'): Finds close values for sensor PRV1-2B.PRV Flow Rate

Examples Reference Chart:

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.
