.. _auto_curves_lastcurve:

*GET THE LAST CURVE FROM A COLLECTION OF CURVES*
================================================

Extracts the last curve from an ordered collection of curves. Use this worker when you need to isolate the final curve in a curve group, for example after a sequence of transformations or filtered results.

When to use
-----------

Classification: **process**.

Tagged: ``collection``, ``curve``, ``curve_group``, ``index``, ``last``, ``slice``.

     - —
     - 
     - Ordered collection of curves (curve group) from which the last curve will be extracted; accepts multiple curves and is optional — if omitted or empty the output will be empty.
