.. _auto_curves_format_points:

*FORMAT THE POINTS FOR ALL CURVES*
==================================

Applies printf-style format strings to the X and Y point values of one or more curves, controlling the numeric precision or string representation of each axis. Use this worker when you need to standardise decimal places or numeric notation across a batch of curves before downstream processing or reporting.

     - curveswhosepointsaretobeformatted
     - vector
     - —
     - 
     - One or more input curves whose point coordinates will be reformatted; accepts a vector (list) of curve objects — leave empty to pass through unchanged.
   * - X Format
     - x_format
     - scalar
     - %s
     - 
     - Printf-style format string applied to every X-axis point value (e.g. '%.4f' for 4 decimal places, '%e' for scientific notation); defaults to '%s' which leaves values unchanged.
   * - Y Format
     - y_format
     - scalar
     - %s
     - 
     - Printf-style format string applied to every Y-axis point value (e.g. '%.4f' for 4 decimal places, '%e' for scientific notation); defaults to '%s' which leaves values unchanged.
