# series.pie.findNearestPointBy

Determines whether the series should look for the nearest point in both dimensions or just the x-dimension when hovering the series. Defaults to `'xy'` for scatter series and `'x'` for most other series. If the data has duplicate x-values, it is recommended to set this to `'xy'` to allow hovering over all points.

Applies only to series types using nearest neighbor search (not direct hover) for tooltip.
