.. _auto_curve_trim_zeroes:

*REMOVE LEADING AND TRAILING ZEROES*
====================================

Removes leading and trailing zero-valued data points from a curve, returning a trimmed curve that starts and ends on non-zero values. Use this worker to clean up curves that contain unnecessary zero padding at either end before further processing or analysis.

When to use

     - The input X-Y curve (vector pair) from which leading and trailing zero-valued points will be stripped; accepts any curve format supported by the platform.
