GROUP_BY_TIME

Description

Converts vector to a grouped vector, by gouping by timespans, so that we have a list of events per timespan. The timespan either is fixed on the latest event, or can be fixed on another time if specified.

GROUP_BY_TIME(Vector<Event>, Scalar<Timespan>)

GROUP_BY_TIME(vector: Vector<Event>, timespan: Scalar<Timespan>): GroupedVector<Time,Event>

Groups the events in the given vector in spans defined by timespan, starting from the latest event.

Parameters

Parameter	Description
vector	A vector of type Event
timespan	A timespan in which the events should be grouped

Returns

A GroupedVector of type <Time, Event>.

GROUP_BY_TIME(Vector<Event>, Scalar<Timespan>, Scalar<Time>)

GROUP_BY_TIME(vector: Vector<Event>, timespan: Scalar<Timespan>, time: Scalar<Time>): GroupedVector<Time,Event>

Group the vector in the given timespans starting at the given time.

Parameters

Parameter	Description
vector	A vector of type Event
timespan	A timespan in which the events should be grouped
time	The time form which we want to start grouping.

Returns

A GroupedVector of type <Time, Event>.

Examples

Group events in 1h spans starting from latest event

GROUP_BY_TIME($GridPowerConsumption, 1h)

Group events in 1d spans on full day spans (i.e. 00:00-23:59)

GROUP_BY_TIME($Produced, 1d, lastZeroHour)
