.. _auto_curves_lookup_yrange_max:

*GET MAX YRANGE*
================

Scans a curve group and returns the maximum Y-range value (i.e., the largest Y-axis span) found across all curves in the group. Use this worker when you need to identify the peak amplitude extent within a set of curves for normalization, scaling, or quality-check purposes.

When to use

Inputs

     - Required
     - Description
   * - Curve Group
     - curve_group
     - vector
     - —
     - 
     - One or more curves whose Y-range will be evaluated; supply any curve group (e.g., time-history or force-displacement curves) — leave empty/optional if no curves are available, in which case the worker returns no result.

Outputs

   * - curves_lookup_scalar_output_1
     - curves_lookup_scalar_output_1
     - scalar
     - Scalar numeric value representing the maximum Y-range (max Y minus min Y) found across all curves in the input group; unitless — inherits the Y-axis units of the supplied curves.
