.. _auto_curve_lag:

*COMPUTE THE LAG VALUES*
========================

Computes the lag (time-shift) of an input curve by a specified number of samples. Use this worker to shift a curve forward along its x-axis by a discrete integer number of steps, producing a delayed version of the original signal.

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

Classification: **process**.

Tagged: ``curve``, ``delay``, ``lag``, ``signal``, ``time-shift``, ``transform``.

     - 
     - Input curve (x/y vector) to be lagged; accepts any time-history or signal curve from upstream workers.
   * - Lag
     - lag

     - Integer number of samples by which to shift the curve forward along the x-axis; defaults to 1 (one-sample delay).
