.. _auto_curves_min:

*MIN OF ALL CURVES*
===================

Computes the element-wise minimum across a collection of curves, returning a single envelope curve whose Y value at each X is the lowest value among all inputs. Optionally synchronises X axes before comparison and supports cylindrical coordinates.

     - 
     - Collection of two or more input curves (vector/time-history format) over which the element-wise minimum is computed; supply at least two curves for a meaningful result.
   * - Sync X
     - sync_x
     - string
     - no
     - 
     - Whether to resample all curves onto a common X axis before comparison ('yes') or assume they already share the same X grid ('no', default); set to 'yes' when curves have different time/X steps.
   * - Use Cylindrical Coords
     - use_cylindrical_coord
     - string
     - no
     - 
     - Whether to interpret curve coordinates in cylindrical rather than Cartesian space before computing the minimum ('yes') or treat them as Cartesian ('no', default); set to 'yes' when curves represent radial/angular data.

     - Single output curve whose Y value at each X position is the minimum of all input curves' Y values at that X — the lower envelope of the input curve set.
