.. _auto_curves_zone_values:

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

Computes aggregate zone values (average, min, max, first, or last) for one or more curves over user-defined x-axis ranges. Use this worker to extract scalar summaries from time-history or signal curves within specific x-interval "zones".

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

Classification: **process**.

Tagged: ``average``, ``curve_aggregation``, ``max``, ``min``, ``signal_summary``, ``x_range``, ``zone_values``.

     - Colon-separated x-axis range(s) defining each zone (e.g. '0:10:20:30' for two zones [0–10] and [20–30]); leave blank to span the full curve extent.
   * - Type
     - type
     - integer
     - average
     - 
     - Aggregation method applied within each zone: one of 'average' (default), 'min', 'max', 'first', or 'last'.
   * - Names

     - 
     - Comma-separated labels to assign to each zone in the output dataset; defaults to the source curve names when left blank.
