.. _auto_curve_partition:

*PARTITION A CURVE AND RETURN A SINGLE VALUE FOR EACH PARITION*
===============================================================

Splits an input curve into a specified number of equal intervals and reduces each partition to a single representative scalar value (average, maximum, or minimum). Use this worker when you need to summarise a time-history or XY curve into discrete segment-level statistics for downstream comparison or KPI extraction.

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

Classification: **process**.

Tagged: ``average``, ``curve``, ``interval``, ``maximum``, ``minimum``, ``partition``, ``reduce``, ``time-history``.

Inputs
------

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

   * - Label
     - ID
     - Type
     - Default
     - Required
     - Description
   * - Curve
     - curve
     - vector
     - —
     - ✓
     - The input XY / time-history curve (vector) to be partitioned; must be provided before the worker executes.
   * - Number Of Intervals
     - intervals
     - scalar
     - 4
     - 
     - Number of equal partitions to divide the curve into; default is 4. Supply a negative value to interpret the number as a time increment rather than a count.
   * - Partition Type
     - partition_type
     - scalar
     - average
     - 
     - Reduction function applied within each partition: 'average' (default), 'maximum', or 'minimum'.

Outputs
-------

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

   * - Label
     - ID
     - Type
     - Description
   * - curve_partition_output_1
     - curve_partition_output_1
     - vector
     - Output curve (vector) whose X-values represent the centre or boundary of each partition and whose Y-values are the computed representative scalar (average, max, or min) for that partition.
