.. _auto_curve_offsetandscale:

*PERFORM AN OFFSET FOLLOWED BY SCALE FOR X AND Y AS SPECIFIED BELOW*
====================================================================

Applies an offset followed by a scale to both the X and Y axes of an input curve. For each axis, the offset is added first, then the result is multiplied by the scale factor. Use this worker for unit conversions, time-shifting, or amplitude normalisation of time-history curves.

     - curvetobescaled
     - vector
     - —
     - 
     - Input curve (X/Y vector pair) to be transformed; supply any time-history or XY curve — the offset and scale parameters are applied to this curve in-place.
   * - X Offset
     - x_offset
     - float
     - 0
     - 
     - Scalar offset added to every X value before scaling (dimensionless or in the curve's X units); default 0 leaves X values unchanged prior to scaling.
   * - Y Offset
     - y_offset
     - float
     - 0
     - 
     - Scalar offset added to every Y value before scaling (dimensionless or in the curve's Y units); default 0 leaves Y values unchanged prior to scaling.
   * - X Scale
     - x_scale
     - float
     - 1
     - 
     - Multiplicative scale factor applied to each (X + x_offset) value; default 1.0 produces no scaling — set to e.g. 0.001 to convert milliseconds to seconds.
   * - Y Scale
     - y_scale
     - float
     - 1
     - 
     - Multiplicative scale factor applied to each (Y + y_offset) value; default 1.0 produces no scaling — set to e.g. 9.81 to convert g to m/s².

     - vector
     - Transformed output curve (X/Y vector pair) where every point satisfies X_out = (X_in + x_offset) × x_scale and Y_out = (Y_in + y_offset) × y_scale.
