.. _auto_curves_map:

*GET A CUSTOM VALUE BASED ON CURVE VALUES*
==========================================

Applies a user-defined map function to one or more input curves to produce a custom derived value or transformed curve. Use this worker when you need to compute a bespoke scalar or curve output from existing curve data using an arbitrary expression.

When to use

Classification: **process**.

Inputs
------

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

   * - Label
     - ID
     - Type
     - Default
     - Required
     - Description
   * - Curve
     - curves
     - vector
     - True
     - 
     - One or more input curves (x/y vector pairs) to which the map function will be applied; accepts multiple curve objects — leave unset if curves will be provided dynamically at runtime.
   * - Map Function
     - map_function
     - text
     - —
     - 
     - A string expression defining the custom mapping logic to apply to the supplied curves (e.g., a mathematical formula or lookup rule); leave blank only if the transformation is handled externally before this worker runs.

Outputs
-------

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

   * - Label
     - ID
     - Type
     - Description
   * - curves_map_output_1
     - curves_map_output_1
     - vector
     - The resulting curve or scalar value produced by applying the map function to the input curves; format mirrors the input vector structure with transformed y-values.
