.. _auto_curve_compress_x:

*NORMALIZE AND SCALE X VALUES*
==============================

Normalizes and scales the X-axis values of a curve by multiplying each X value by a user-supplied scale factor. Use this worker to compress or expand the time/frequency axis of a curve before further processing or comparison.

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

Classification: **process**.

Tagged: ``compress``, ``curve``, ``normalize``, ``scale``, ``transform``, ``x-axis``.

Inputs
------

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

   * - Label
     - ID
     - Type
     - Default
     - Required
     - Description
   * - Curve To Be Normalized
     - curvetobenormalized
     - vector
     - —
     - 
     - Input curve (X/Y vector) whose X values will be scaled; accepts any d3VIEW curve object — leave unconnected only if the worker is used in a passthrough chain.
   * - Scale X
     - scalex
     - scalar
     - 1.0
     - 
     - Multiplicative scale factor applied to every X value of the curve (dimensionless); default 1.0 leaves X values unchanged — set to values <1 to compress or >1 to expand the X axis.

Outputs
-------

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

   * - Label
     - ID
     - Type
     - Description
   * - curve_compress_x_output_1
     - curve_compress_x_output_1
     - vector
     - Output curve identical in structure to the input but with all X values multiplied by the scale factor; Y values are preserved unchanged.
