.. _auto_curve_get_x:

*GET X-POINTS FROM CURVE*
=========================

Extracts the x-coordinate vector from a given curve object. Use this worker when you need the independent-axis (abscissa) values of a curve as a standalone vector for further processing or analysis.

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

Classification: **process**.

Tagged: ``abscissa``, ``curve``, ``extraction``, ``vector``, ``x-points``.

     - —
     - 
     - Input curve object (x–y pair) from which the x-coordinates will be extracted; optional — leave unconnected only if downstream logic handles a null vector gracefully.

Outputs

     - curve_get_x_output_1
     - vector
     - Ordered vector of x-axis values (abscissa points) extracted from the input curve, preserving the original sampling order and units.
