gettsbeforeevent - New timeseries object with samples occurring before event

Syntax

Description

ts1 = gettsbeforeevent(ts,event) returns a new timeseries object ts1 with samples occurring before an event in ts, where event can be either a tsdata.event object or a string. When event is a tsdata.event object, the time defined by event is used. When event is a string, the first tsdata.event object in the Events property of ts that matches the event name specifies the time.

ts1 = gettsbeforeevent(ts,event,n) returns a new timeseries object ts1 with samples occurring before an event in ts, where n is the number of the event occurrence with a matching event name.

Tips

When the timeseries object ts contains date strings and event uses numeric time, the time selected by the event is treated as a date that is calculated relative to the StartDate property in ts.TimeInfo.

When ts uses numeric time and event uses calendar dates, the time selected by the event is treated as a numeric value that is not associated with a calendar date.
