.. _auto_curve_normalize:

*NORMALIZE THE CURVE BY DIVIDING THE Y-VALUES BY THE MAX-Y*
===========================================================

Normalizes a curve's x, y, or both axes using either min-max scaling (divide by max value) or standard-scaler (z-score) normalization. Use this worker to bring curve values into a comparable range before further processing or comparison.

Inputs

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

     - Default
     - Required
     - Description
   * - Curve 1
     - curve1
     - vector
     - —
     - 
     - Input curve (x/y vector) to be normalized; supply any time-history or response curve that requires axis scaling.
   * - Axis
     - axis
     - string
     - x
     - 
     - Axis to normalize: 'x' normalizes only x-values, 'y' normalizes only y-values, 'xy' normalizes both axes; defaults to 'x'.
   * - Normalizetype
     - normalizetype
     - string
     - minmax
     - 
     - Normalization method: 'minmax' divides each value by the axis maximum (range 0–1), 'standardscaler' applies z-score standardization (zero mean, unit variance); defaults to 'minmax'.
