.. _auto_curves_switchx:

*SWITCH X POINTS*
=================

Replaces the X-values of a base curve with the X-values taken from a second reference curve, keeping the original Y-values intact. Use this worker when two curves share the same number of points and X-range but you need to re-key one curve onto the other's X-axis.

When to use

     - The curve whose Y-values are preserved while its X-values are replaced; must have the same number of points and X-range as the reference curve.

     - —
     - 
     - The reference curve whose X-values will be substituted into the base curve; must match the base curve in point count and X-range.
