.. _auto_curve_scaleandoffset:

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

Applies an independent scale and offset to both the X and Y axes of a curve, computing `new_x = x_scale * (x + x_offset)` and `new_y = y_scale * (y + y_offset)`. Use this worker whenever a curve needs unit conversion, axis normalisation, or a simple affine transformation.

     - —
     - 
     - Input curve (X/Y vector pair) to be transformed; must be provided as a d3VIEW curve object — all scale and offset operations are applied to this curve.
   * - X Scale
     - x_scale
     - float
     - 1.0

     - Multiplicative scale factor applied to each X value after the X offset is added (dimensionless float); default 1.0 leaves X magnitude unchanged.
   * - Y Scale
     - y_scale
     - float
     - 1.0
     - 
     - Multiplicative scale factor applied to each Y value after the Y offset is added (dimensionless float); default 1.0 leaves Y magnitude unchanged.
   * - X Offset
     - x_offset
     - float
     - 0.0
     - 
     - Constant value added to every X coordinate before scaling (same units as the X axis); default 0.0 applies no shift.
   * - Y Offset
     - y_offset
     - float
     - 0.0
     - 
     - Constant value added to every Y coordinate before scaling (same units as the Y axis); default 0.0 applies no shift.
