.. _auto_curves_lookup_yvalueat_from_dataset:

*LOOKUP Y-VALUE FROM A GIVEN X-VALUE*
=====================================

Looks up the interpolated y-value on one or more curves at each x-value supplied by a dataset column. Use this worker to extract point responses from simulation or test curves at a set of predefined x-locations stored in a tabular dataset.

     - vector
     - —
     - ✓
     - One or more curves (x/y pairs) from which y-values will be interpolated; accepts multiple curve objects — each curve will be evaluated at every x-value provided by the dataset column.

     - —
     - ✓
     - Tabular dataset containing the x-values at which the lookup is performed; must include at least the column specified in the 'col' input.
   * - Column With X-Values
     - col
     - text
     - —
     - ✓
     - Name of the column within the dataset that holds the x-values to look up; select the appropriate column from the dataset's available headers.
