.. _auto_curves_set_constant_y_value:

*SET CONSTANT Y-VALUE TO ALL X-POINTS IN ALL CURVES*
====================================================

Sets every Y value across all X points in a batch of curves to a single user-specified constant, effectively flattening each curve to a horizontal line. Use this worker to zero-out, baseline, or override Y data on one or more curves in a single step.

When to use
-----------

Classification: **process**.

     - 
     - One or more input curves whose Y values will be overwritten; accepts any curve type supported by the platform (leave empty if curves will be piped in from an upstream worker).
   * - Constant Y-value
     - y_value
     - text
     - 0
     - 
     - The scalar constant that will be assigned to every Y point of every input curve (dimensionless numeric; defaults to 0 if left blank).
