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

If you have several series of one type, you can set selection 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 selection style option for an individual series, use the selectionStyle 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
• Predefined SVG colors

The following values are available.

• solid
  Displays a solid, continuous line.
• longDash
  Displays the series using long dashes.
• dash
  Displays the series using dashes.
• dot
  Displays the series using dots.
• any combination of 'longDash', 'dash' and 'dot'
  Displays the series by repeating the specified combination. For instance, 'dashdotdash'.

Use the DashStyle enum to specify this option when the widget is used as an ASP.NET MVC Control. This enum accepts the following values: Solid, LongDash, Dash, and Dot.
