.. _auto_curves_trim_x:

*CREATE A CURVE FROM SET*
=========================

Trims one or more curves along the X-axis so that their length matches a reference curve. Use this worker to synchronise the domain of a set of curves to a common reference before comparison or further processing.

When to use

Inputs

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

     - Required
     - Description
   * - Curve To Be Trimmed
     - curve_to_be_trimmed
     - vector
     - —
     - 
     - One or more input curves (vector) whose X-axis extent will be trimmed to match the reference curve; accepts multiple curves simultaneously.
   * - Reference Curve
     - reference_curve
     - vector
     - —
     - 
     - The reference curve (vector) that defines the target X-axis extent or number of points to which the input curves will be trimmed.
   * - Sync Type
     - sync_type
     - scalar
     - num_of_points
     - 
     - Trimming strategy: 'num_of_points' trims the input to the same number of data points as the reference (default), while 'x' trims to match the reference's X-axis range.
