.. _auto_curves_lookup_xatyabsmax:

* COMPUTE THE VALUE OF X FOR A GIVEN Y VALUE*
=============================================

Finds the X value corresponding to the absolute maximum Y value on one or more input curves. Use this worker when you need to identify the time or position at which a curve reaches its peak absolute amplitude.

When to use

     - One or more input curves (vector format) from which the X value at the absolute Y maximum will be extracted; accepts multiple curves when batch lookup is needed.
