TL GetActive: Difference between revisions

Line 1:

This reserved word returns a numeric value representing the ID of the currently active trendline.

TL_GetActive returns -1 if no trendlines are currently selected or were added to a chart yet.

If an active trendline is removed from a chart then TL_GetActive returns -1.

If an inactive trendline is removed from a chart then TL_GetActive returns the object ID number of the currently active trendline.

== Usage ==

<syntaxhighlight>TL_GetActive</syntaxhighlight>

== Notes ==

* When the reserved word performs its operation successfully, trendline ID is returned.

* When a reserved word cannot perform its operation, it returns an error code.

* TL_GetActive should be assigned to a [[Variable|numeric variable]] or [[Array|array]] in order to determine if the operation is performed successfully. In other words, if the returning value of TL_GetActive isn't saved, it's not possible to check whether or not the selection of the trendline succeeded.
