.. _auto_curve_xvalues:

*RETURN THE XVALUES AS A VECTOR*
================================

Extracts and returns the x-values of an input curve as a numeric vector. Use this worker whenever you need the independent-axis data (e.g. time, displacement) from a curve object for downstream processing.

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

Classification: **process**.

Tagged: ``curve``, ``extract``, ``transform``, ``vector``, ``xvalues``.

Inputs
------

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

   * - Label
     - ID
     - Type
     - Default
     - Required
     - Description
   * - Curve 1
     - curve1
     - vector
     - —
     - 
     - The input curve object from which x-values will be extracted; accepts any curve type (e.g. time-history, force-displacement) — leave unconnected if the curve is supplied implicitly by the calling workflow.

Outputs
-------

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

   * - Label
     - ID
     - Type
     - Description
   * - curve_xvalues_output_1
     - curve_xvalues_output_1
     - set
     - Ordered numeric vector containing all x-axis values of the input curve (e.g. time in ms, displacement in mm), preserving the original sampling points and sequence.
