.. _auto_curve_integrate_if_positive:

*INTEGRATE POSITIVE VALUES*
===========================

Integrates only the positive portions of a curve, treating negative values as zero before integration. Use this worker when you need the cumulative area contributed exclusively by positive signal values, such as positive velocity impulse or positive force-displacement work.

When to use

     - Input curve (X/Y vector) whose positive Y-values will be integrated; negative values are ignored. Leave optional if the curve is piped directly from an upstream worker.
