hoverStyle

To set a custom 'hover' style for all series at once, use the hoverStyle object within the commonSeriesSettings configuration object.

If you have several series of one type, you can set hover style options to the values specific to this type using the corresponding object (area, line or another) within the commonSeriesSettings configuration object. The values that are set within series-type-specific configuration objects override the corresponding common values.

In case you have to set a hover style option for an individual series, use the hoverStyle 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 (not supported in Internet Explorer 8)
• Predefined/cross-browser color names
• Predefined SVG colors (not supported in Internet Explorer 8)

Within this object, you can specify how to apply hatching using the direction option, the width and opacity of lines with the width and opacity options, and the space between the lines using the step option.
