.. _auto_curves_bin_values:

*BIN VALUES OF CURVE*
=====================

Bins the Y-values of one or more curves into a fixed number of intervals and summarises each bin using a selected aggregation method (average, max, first, or last Y value). Use this worker to reduce curve data into histogram-style datasets for statistical analysis or visualisation.

   * - Curves To Bin
     - curves
     - vector
     - —
     - 
     - One or more input curves whose Y-values will be binned; accepts the standard d3VIEW curve vector format — leave empty only if curves are supplied dynamically upstream.
   * - Bin Type
     - bin_type
     - string
     - yavg
     - 
     - Aggregation method applied within each bin: 'yavg' (mean), 'ymax' (maximum), 'yfirst' (first sample), or 'ylast' (last sample); defaults to 'yavg'.
   * - Number Of Bins
     - numberofbins
     - scalar
     - 10
     - 
     - Integer number of equal-width bins to divide the Y-value range into; defaults to 10 — increase for finer resolution, decrease for coarser grouping.
   * - Postfix
     - prefix
     - scalar
     - —
     - 
     - Optional string prepended to the output curve/column label to distinguish the binned result; leave blank (default) to use no prefix.
   * - Postfix
     - postfix
     - scalar
     - —
     - 
     - Optional string appended to the output curve/column label to distinguish the binned result; leave blank (default) to use no postfix.
