TIMEAGGREGATE¶

Aggregates number values over a specified time period. Timeaggregate saves the aggregated interval values in a TargetRange. The returned value in the cell is aggregated over all numbers within the periode.

Syntax

TIMEAGGREGATE(DataCell, [Period, AggregationMethod, TimeSerial, Interval, TargetRange])

Arguments

Name Description
DataCell The data source cell which should evaluate to a number. All other values are ignored.
Period Optional. The time period in seconds in which data is collected. Defaults to 60 seconds.
AggregationMethod Optional. One of the predefined numbers which specifies the aggregation method to use. Defaults to 9.
TimeSerial Optional. A serial number to use as key for each aggregated value. Defaults to NOW.
Interval Optional. An interval in seconds at which values should be aggregated. Defaults to the specified period. To not loose any data, an Interval should always be a divisor of the Period. Note: Default Interval collects a different TargetRange as a handwritten equal Period. Default Interval: collects all values within the specified Period. Interval equals Period: aggregates all values to one value.
TargetRange Optional. A cell range to write the aggregated values to. Collects aggregation intervals and displays them. Differs if interval is left blank (see interval).

Aggregation Methods

Number Method Description
0 NONE No aggregation is performed and the last valid value of specified DataCell is returned.
1 AVERAGE Calculates the average of all received values.
2 COUNT Counts the number of received values.
3 COUNTA Counts all values which are not zero.
4 MAX Determines the maximum of all received values.
5 MIN Determines the minimum of all received values.
6 PRODUCT Calculates the product of all received values.
7 STDEV.S Calculates the standard deviation of all recieved values.
8 STDEV.P Currently not available!!
9 SUM Calculates the sum of all received values.

Return Value

A number value aggregated over all values within specified period.

Example

Function Comment
=TIMEAGGREGATE(C2, 20) Calculates the sum of all values read from C2 over a period of 20 seconds.
=TIMEAGGREGATE(C2, 20, 1,,2, D4:E14) Calculates the average each 2 seconds and writes roughly 10 values to target range D4:E14
