.. _auto_curves_max_min_normalize:

*COMPUTE MAX-MIN NORMALIZE*
===========================

Applies min-max normalization to one or more curves, rescaling values to the [0, 1] range. The normalization can be applied to the X axis, Y axis, or both axes simultaneously. Use this worker to standardize curve magnitudes before comparison, plotting, or machine-learning preprocessing.

Inputs

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

     - Default
     - Required
     - Description
   * - Curve
     - curve
     - vector
     - —
     - 
     - One or more input curves whose values will be min-max normalized; accepts multiple curve objects (vector type) — leave empty only if curves are supplied downstream at runtime.
   * - Axes
     - axes
     - list
     - xy
     - 
     - Axis or axes to normalize: 'xy' (default) rescales both X and Y to [0, 1], 'x' rescales only the X axis, and 'y' rescales only the Y axis.

Outputs

   * - curves_max_min_normalize_output_1
     - curves_max_min_normalize_output_1
     - vector
     - The normalized curve(s) with selected axis/axes rescaled to [0, 1], returned as a vector in the same structure as the input curves.
