jQuery PolarChart - StackedBarSeries.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 properties 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 property 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.

To set custom border settings specific to the 'hovered' state for all series at once, use the properties of the commonSeriesSettings.hoverStyle.border configuration object.

To set custom border settings specific to the 'hovered' state for 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 property for a 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 property supports the following colors:

• Hexadecimal colors
• RGB colors
• RGBA colors
• Predefined/cross-browser color names
• Predefined SVG colors
• Paint server address

You can also specify a custom pattern or gradient instead of a plain color. Call the registerPattern() or registerGradient() method to obtain a fill ID. Assign that value to the fillId field.

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