.. _auto_curve_overlay_with_derivative:

*OVERLAY WITH ITS DERIVATIVE*
=============================

Computes the derivative of an input curve and overlays it alongside the original, returning both as a combined vector output. Use this worker to visually compare a signal with its rate of change in a single plot.

When to use

     - The input curve (X/Y vector) to be differentiated and overlaid; accepts any time-history or scalar signal — leave as default (null) if the curve will be wired at runtime.
