.. _auto_curve_compress_y:

*NORMALIZE AND SCALE Y VALUES*
==============================

Normalizes and scales the Y values of a curve by a given scalar multiplier. Use this worker when you need to compress, expand, or normalize the amplitude of a curve before further processing or comparison.

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

Classification: **process**.

Inputs
------

.. list-table::
   :header-rows: 1
   :widths: 20 20 20 20 20 20

     - Default
     - Required
     - Description
   * - Curve To Be Normalized
     - curvetobenormalized
     - vector
     - —
     - 
     - The input curve whose Y values will be scaled; provide as an XY vector (e.g., time-history or force-displacement curve). Optional — leave empty only if the curve is supplied programmatically upstream.
   * - Scale Y
     - scale_y
     - scalar
     - 1.0
     - 
     - Scalar multiplier applied to every Y value of the curve (dimensionless); defaults to 1.0 (no change). Set to values less than 1 to compress, greater than 1 to expand the amplitude.

     - curve_compress_y_output_1
     - vector
     - The transformed curve with Y values multiplied by scale_y; retains the original X values and units of the input curve.
