.. _auto_curve_moving_average:

*MOVING AVERAGE OF Y-VALUES*
============================

Smooths a curve by computing a rolling (moving) average over its Y-values. Use this worker to reduce noise in time-history or signal data by averaging each point over a configurable window of neighboring steps.

     - Input XY curve (vector) whose Y-values will be smoothed; typically a time-history or signal curve in any engineering unit.
   * - Number Of Steps
     - num_steps
     - scalar
     - 10
     - 
     - Window size (number of steps) for the rolling average; defaults to 10 — increase for heavier smoothing, decrease to preserve more detail.
