ENFORCES MONOTONICITY FOR X OR Y POINTS

Enforces monotonicity on a curve’s X or Y axis by removing non-monotonic points according to the chosen axis mode and direction. Use this worker to clean up curves with oscillations or back-tracking before further processing or material calibration workflows.

When to use

Classification: process.

Tagged: cleanup, curve, curve_transform, monotonic, monotonicity, oscillation, x-axis, y-axis.

Inputs

Label	ID	Type	Default	Required	Description
Curve To Be Operated On	curvetobeoperatedon	vector	—		The input curve (X/Y vector pair) whose monotonicity will be enforced; must be supplied as a two-column vector — leave unconnected only if the curve is piped implicitly by the parent workflow.
Axis And Starting Point	axis	string	x		Axis and traversal strategy for monotonicity enforcement: ‘x’ / ‘y’ / ‘xy’ start from the first point and enforce increasing monotonicity; ‘x1’ removes horizontal oscillations; ‘x_end’ / ‘y_end’ start from the last point; ‘yslope’, ‘yslopeclip’, and ‘yslopeconstant’ enforce slope-based monotonicity with different clipping behaviours; defaults to ‘x’.
Min X	xmin	scalar	-1e20		Minimum X value below which curve points are ignored before the monotonicity filter is applied; dimensionless scalar matching the curve’s X units — leave at default (-1e20) to include all points.

Outputs

Label	ID	Type	Description
curve_monotonic_output_1	curve_monotonic_output_1	vector	The monotonicity-enforced output curve (X/Y vector pair) with non-monotonic points removed or adjusted according to the selected axis mode and direction.
