.. _auto_curve_get_rise_saturation:

*GET THE ENCLOSED AREA FROM COORDINATES*
========================================

Computes the rise and saturation characteristics of a curve by detecting the crush start and end points (i.e., the enclosed region between onset and plateau). Use this worker to extract rise/saturation metrics from force-displacement or similar response curves.

     - Input XY curve (e.g. force-displacement or stress-strain) from which rise onset and saturation end points will be identified; accepts a vector curve object — leave empty if chaining from an upstream curve output.
