plotOptions.series.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.
