To set custom border settings specific to the 'hovered' state for points in all series at once, use the properties of the commonSeriesSettings | point | hoverStyle | border configuration object.
To set custom border settings specific to the 'hovered' state for points in all series of a single type at once, use the properties of the corresponding object within commonSeriesSettings (e.g. area | hoverStyle | border). The values that are set within this object override the corresponding common values that are set within the root commonSeriesSettings | hoverStyle | border object.
In case you have to set a hover style option for a point border in an individual series, use the hoverStyle | border object within the series object of the series array. The values that are set individually override corresponding common values.
This option supports the following colors.
- Hexadecimal colors
- RGB colors
- RGBA colors
- Predefined/cross-browser color names
