*COMPUTE THE CROSS PLOT OF THE Y WITH ITS DERIVATIVE*
=====================================================

Computes the cross-plot of a curve's Y values against its own derivative (dY/dX), producing a phase-plane style vector output. Use this worker to visualise the rate-of-change relationship of a signal against its instantaneous values, e.g. for identifying turning points or damping characteristics.
