.. _auto_curve_offset_and_scale:

*OFFSET AND SCALE THE X-VALUES AND Y-VALUES BY THE FACTORS PROVIDED BELOW*
==========================================================================

Applies independent offset and scale factors to both the X and Y values of a curve, in that order: offset is added first, then the result is multiplied by the scale factor. Use this worker to shift and/or rescale any curve's axes during pre- or post-processing.

     - Input curve (vector of X/Y pairs) to be transformed; all offset and scale operations are applied to this curve.
   * - X Offset Value
     - x_offsetvalue
     - scalar
     - 0.0

     - Scalar added to every X value before scaling is applied; dimensionless additive shift — default 0.0 (no offset).
   * - Y Offset Value
     - y_offset
     - scalar
     - 0.0
     - 
     - Scalar added to every Y value before scaling is applied; dimensionless additive shift — default 0.0 (no offset).
   * - X Scale Value
     - x_scalevalue
     - scalar
     - 1.0
     - 
     - Multiplicative factor applied to every X value after the X offset; default 1.0 (no scaling).
   * - Y Scale Value
     - y_scalevalue
     - scalar
     - 1.0
     - 
     - Multiplicative factor applied to every Y value after the Y offset; default 1.0 (no scaling).
