Angular PolarChart - series.point.selectionStyle

The PolarChart UI component comes with API members that allow you to select a point in code. To set a custom 'selected' style for points in all series at once, use the point.selectionStyle object within the commonSeriesSettings configuration object.

If you have several series of one type, you can set point selection style properties to the values specific to the series 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 point selection style property for an individual series, use the selectionStyle object within the series.point object of the series array. The values that are set individually override corresponding common values.

To set custom border settings specific to the 'selected' state for points in all series at once, use the properties of the commonSeriesSettings.point.selectionStyle.border configuration object.

To set custom border settings specific to the 'selected' state for points in all series of a single type at once, use the properties of the corresponding object within commonSeriesSettings (e.g. area.selectionStyle.border). The values that are set within this object override the corresponding common values that are set within the root commonSeriesSettings.selectionStyle.border object.

In case you have to set a selection style property for a point border in an individual series, use the selectionStyle.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.
