.. _auto_curve_sort:

*SORT POINTS*
=============

Sorts the points of a curve along a chosen axis (X or Y) in ascending or descending order. Use this worker to reorder disordered curve data before further processing or plotting.

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

Classification: **process**.

Tagged: ``ascending``, ``curve``, ``descending``, ``points``, ``reorder``, ``sort``, ``transform``.

Inputs
------

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

   * - Label
     - ID
     - Type
     - Default
     - Required
     - Description
   * - Curve
     - curve
     - vector
     - —
     - 
     - Input curve (X/Y vector) whose points will be sorted; connect any curve output from an upstream worker.
   * - Choose Axis
     - axis_type
     - scalar
     - y
     - 
     - Axis to sort by — 'y' (default) sorts on the Y values, 'x' sorts on the X values.
   * - Choose Axis
     - order
     - scalar
     - asc
     - 
     - Sort direction — 'asc' (default) for ascending order, 'desc' for descending order.

Outputs
-------

.. list-table::

   * - Label
     - ID
     - Type
     - Description
   * - curve_sort_output_1
     - curve_sort_output_1
     - vector
     - Sorted curve with the same X/Y points as the input but reordered according to the selected axis and direction.
