.. _auto_curves_add_pairs:

*ADD PAIRS OF CURVES*
=====================

Adds pairs of curves element-wise by matching curves from Curve Group 1 and Curve Group 2 positionally and summing their Y values over a common X axis. Use this worker when you need to superimpose or combine two collections of curves pair-by-pair (e.g. adding a baseline signal to a perturbation signal for each channel).

   * - Curve 1
     - curve_group1
     - vector
     - —
     - 
     - First collection of curves (Curve Group 1); each curve is matched positionally with the corresponding curve in Curve Group 2 and its Y values are used as the first addend. Accepts one or more curves; leave empty only if no first operand is needed.
   * - Curve 2
     - curve_group2
     - vector
     - —
     - 
     - Second collection of curves (Curve Group 2); each curve is matched positionally with the corresponding curve in Curve Group 1 and its Y values are used as the second addend. Must contain the same number of curves as Curve Group 1 for pair-wise addition.
