.. _auto_curve_insert_point_at_x:

*INSERT POINT AT X*
===================

Inserts one or more interpolated points into a curve at specified X-axis positions, preserving the original data while adding new (x, y) pairs computed by interpolation. Use this worker when a curve must contain exact values at particular X locations before downstream processing or comparison.

     - The source curve (X/Y vector pair) into which new points will be inserted; must be a valid d3VIEW curve object.
   * - X-Value
     - x_value
     - scalar

     - The X-axis position(s) at which to insert interpolated points; accepts a single numeric value (default 0) or a comma-separated list (e.g. 1,2,3) for multiple insertions.
