.. _auto_curve_map:

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

Applies a user-defined mathematical map function to every value in an input curve, returning a transformed curve. Use it to clamp, scale, or otherwise remap curve data with custom expressions such as MAX(X,1) or X*2+offset.

Inputs
------

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

   * - Label
     - ID
     - Type
     - Default
     - Required
     - Description
   * - Curve
     - curve
     - vector
     - True
     - 
     - Input curve (vector of X/Y pairs) to which the map function will be applied; accepts multiple curves (definedMany=1); leave unconnected only if curve data will be provided by another means.
   * - Map Function
     - map_function
     - text
     - —
     - 
     - Mathematical expression string applied element-wise to each curve value, where X represents the current value (e.g. MAX(X,1) clamps values below 1); leave empty to pass the curve through unchanged.

Outputs
