.. _auto_curve_zone_average:

*COMPUTE ZONE AVERAGE BASED ON X-RANGES*
========================================

Computes the average Y value of a curve within one or more user-defined X-axis zones (ranges). Provide the input curve and a colon-separated list of X range pairs; the worker returns a key-value map of zone averages. Use this to summarise signal levels across specific time or frequency windows.

     - The input curve (X/Y vector) over which zone averages will be computed; typically a time-history or frequency-response curve from a simulation or test.

     - Colon-separated X-axis range pairs defining each zone of interest (e.g. '0:10:20:30' for two zones [0–10] and [20–30]); units must match the curve's X-axis units.

     - Key-value map where each key identifies a zone (by its X range) and the corresponding value is the computed average Y value within that zone.
