*CREATE A NEW CURVE BY LINEAR INTERPOLATION TO REACH A MAXIMUM OF NUM_POINTS SPECIFIED BELOW*
=============================================================================================

Resamples one or more curves stored in a dataset by dividing the x-axis range into a fixed number of equidistant intervals and reducing each interval to a representative scalar (avg, min, max, slope, integral, etc.). Use this worker to normalise curves to a common resolution before comparison, ML feature extraction, or downstream signal processing.

Inputs
------

.. list-table::
   :header-rows: 1
   :widths: 20 20 20 20 20 20

   * - Label
     - ID
     - Type
     - Default
     - Required
     - Description
   * - Dataset that contains the curves to be binned
     - dataset_1
     - dataset
     - —
     - 
     - Input dataset containing one or more curve columns to be binned; each selected column is treated as a y-series against the dataset's x-axis column.
   * - Curve Columns
     - curve_cols
     - text
     - —
     - 
     - One or more column names from dataset_1 that identify the y-value series to bin; supports multi-select driven by the columns present in dataset_1.
   * - Num of Intervals
     - num_points
     - integer
     - 100
     - 
     - Number of equidistant intervals to create between the first and last x-axis point (default 100); the output curve will have num_points+1 boundary points.
   * - Bin Prefix
     - prefix
     - texgt
     - CBIN
     - 
     - String prefix prepended to each output column name to identify binned results (default 'CBIN'), e.g. 'CBIN_force'.
   * - Type of Binned Value between current and previous point
     - type
     - string
     - avg
     - 
     - Aggregation method applied to raw samples that fall within each interval: avg (mean), min, max, diff (end−start), slope, integral, current (last sample), or previous (first sample); default is 'avg'.

   * - Binned Dataset
     - binned_values
     - dataset
     - Dataset containing the resampled curves, one output column per selected input curve column, each named with the specified prefix and containing the aggregated value for every equidistant interval.
