.. _auto_curve_abs:

*CURVE ABS*
===========

Applies the absolute-value operation element-wise to every Y-value of the input curve, leaving the X-axis unchanged. Use this worker whenever a curve may contain negative amplitudes that should be reflected to positive (e.g. signed force or displacement signals).

When to use

     - Input curve (X/Y vector) whose Y-values will be transformed to their absolute values; accepts any numeric time-history or XY signal.
