.. _auto_curve_splitvalues:

*SPLIT THE CURVE INTO SEGMENTS AND RETURN THE Y VALUES FOR THOSE SEGMENTED CURVES*
==================================================================================

Splits a curve into a specified number of equal segments and returns a representative scalar value (average, minimum, or maximum) of the Y values within each segment. Use this worker to reduce a time-history or signal curve into a fixed-length feature vector of segment statistics.

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

Classification: **process**.

Tagged: ``avg``, ``curve``, ``feature-extraction``, ``max``, ``min``, ``segmentation``, ``split``, ``time-history``.

Inputs

     - Default
     - Required
     - Description
   * - Choose Curve To Be Split
     - choose_curvetobe_split
     - vector
     - —
     - 
     - The input curve (X-Y vector) to be divided into segments; accepts any 1-D curve object from the workflow — leave empty only if the curve is piped in from an upstream worker.
   * - Type Of Value To Return
     - typeofvaluetoreturn
     - string
     - avg
     - 
     - Aggregation statistic applied to the Y values within each segment: 'avg' (default) returns the mean, 'min' returns the minimum, and 'max' returns the maximum.
   * - Number Of Splits
     - numberof_splits
     - scalar
     - 10
     - 
     - Integer number of equal-width segments to divide the curve into; defaults to 10 — increase for finer resolution, decrease for a more compact feature vector.

     - keyvalue
     - Key-value map where each key is the segment index (1-based) and the corresponding value is the aggregated Y statistic (avg/min/max) for that segment.
