.. _auto_curves_get_slopes:

*COMPUTE THE SLOPES OF THE CURVES*
==================================

Computes scalar slope values from one or more input curves using a selected aggregation method (first, last, min, max, average, or initial-to-y-max). Use this worker when you need to reduce curve data to a single representative slope metric for downstream KPI rollup or comparison.

When to use

Classification: **process**.

Inputs
------

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

   * - Label
     - ID
     - Type
     - Default
     - Required
     - Description
   * - Curves In
     - curves_in
     - vector
     - —
     - 
     - One or more input curves (vector) whose slopes will be computed; accepts multi-select curve inputs in d3VIEW curve format — leave empty to pass curves dynamically from an upstream worker.
   * - Slope Type
     - slope_type
     - string
     - first
     - 
     - Aggregation method used to extract a single slope value from each curve: 'first' (slope at the first segment, default), 'last' (final segment), 'max' (steepest positive), 'min' (steepest negative), 'avg' (mean of all segment slopes), or 'initialtoymax' (slope from the initial point to the y-maximum).
