jQuery PolarChart - series.border
Series of some types can be displayed with borders (bars, area, etc.). To set custom border settings for all such series at once, use the border object within the commonSeriesSettings configuration object.
If you have several series of one type, you can set border properties specific to this type using the corresponding object (area, line, or another) within the commonSeriesSettings configuration object. In addition, any non-specific series type property of the commonSeriesSettings.border object can be added to the series-type-specific border definition within the commonSeriesSettings.area/line/... | border configuration object. The values that are set within series-type-specific configuration objects override the corresponding common values.
In case you have to set an individual value for a common or series-type-specific border property, use the border object within the series object of the series array. The values that are set individually override corresponding common values.
The following dash styles are available:
The border is a solid, continuous line.
The border is displayed using long dashes.
The border is displayed using dashes.
The border is displayed using dots.
Any combination of 'longDash', 'dash' and 'dot'
The border is displayed by repeating the specified combination. For instance, 'dashdotdash'.
