ScrollXAxis

Scrolls the x-axis by the specified offset value in seconds.

If a negative number is given to the offset value, it is possible to scroll back to the historical data.

This action prevents scrolling outside the limits (start: first data point timestamp, end: freeze time).

If the offset value is not possible, the reason can be checked in result.

•result= 0: The offset specification is OK.

•result= 1: The start time is before the first data point timestamp.

•result= 2: The end time is after the freeze time.

•xAxisId: PropertyCollectionReference

•offset: Number

•result: Number

SetCursorStyle

Applies a predefined style for the cursor collection.

•cursorId: PropertyCollectionReference

•value: StyleReference

SetGraphStyle

Sets a predefined style for the graph collection.

•graphId: PropertyCollectionReference

•value: StyleReference

SetGraphVisible

Controls the visibility of the graph collection that is specified as an argument.

SetXAxisStyle

Applies a predefined style for the x-axis collection.

•xAxisId: PropertyCollectionReference

•value: StyleReference

SetXAxisTime

Defines the start and end time from the x-axis in freeze mode.

•result= 0: The time specifications are OK.

•result= 1: The start time is before the first data point timestamp.

•result= 2: The end time is after the freeze time.

•result= 3: The states from results 1 and 2 occur.

•result= -1: End time ≤ Start time

If the time span is set using action SetXAxisTimeSpan, the time specifications are overwritten.

•xAxisId: PropertyCollectionReference

•start: DateTime

•end: DateTime

•result: Number

SetXAxisTimeSpan

Defines the visible time window of the x-axis in seconds.

If the time span is set using action SetXAxisTime, the set time window (timespan) is overwritten.

•xAxisId: PropertyCollectionReference

•timeSpan: UNumber

SetXAxisVisible
