.. _auto_curve_subtract_from:

*COMPUTE DIFFERENCE BETWEEN TWO CURVES*
=======================================

Computes the element-wise difference between two curves as Curve2 − Curve1 (i.e., "subtract Curve1 from Curve2"). Use this worker when you need the reverse subtraction order compared to a standard subtract operation.

     - Required
     - Description
   * - Curve 2
     - curve1
     - vector
     - —
     - 
     - The curve to subtract (the subtrahend); a time–value or X–Y vector that will be taken away from Curve 2. Must share the same abscissa domain as Curve 2.
   * - Curve 2
     - curve2
     - vector
     - —
     - 
     - The curve to subtract from (the minuend); a time–value or X–Y vector from which Curve 1 is subtracted, yielding Curve2 − Curve1.
