.. _auto_curves_monotonic:

*ENFORCES MONOTOCITY FOR X OR Y POINTS FOR ALL CURVES*
======================================================

Enforces monotonicity on the X or Y axis of one or more input curves by removing back-tracking points or oscillations according to the selected strategy. Use this worker to clean up noisy or non-monotonic test/simulation curves before further processing, interpolation, or material calibration.

Inputs

     - Required
     - Description
   * - Curve To Be Operated On
     - curvetobeoperatedon
     - vector
     - —
     - 
     - One or more input curves (vector format) on which the monotonicity enforcement will be applied; accepts multiple curves in a single pass.
   * - Axis
     - axis
     - string
     - x
     - 
     - Axis and strategy used to enforce monotonicity: 'x' (strict X monotonicity), 'x1' (removes horizontal X oscillations), 'y' (strict Y monotonicity), 'yslope' / 'yslopeclip' / 'yslopeconstant' (slope-based Y corrections), 'x_end' / 'y_end' (trim from the trailing end); defaults to 'x'.
