Vue PolarChart - series.label

Each series point can be accompanied by a text label that represents data related to the point. These are called series point labels. Use the label object's properties to set label options for all chart series at once.

Specify the label object's properties within the commonSeriesSettings configuration object to set label options for all chart series at once.

If you have several series of a single type, you can set label options to the values specific to this series type using the corresponding object (area, line, etc.) within the commonSeriesSettings configuration object. The values that are set within series-type-specific configuration objects override the corresponding common values.

If you need to set a label option for an individual series, use the label object within the series object of the series array. The values that are set individually override the corresponding common values.

You can remove the label's background by setting this option to "none". In this case, the label's text is the same color as the point.

Use this object to make the borders of point labels visible/invisible and set up border options such as color and width.

A series point label can be placed separately, near the represented point. To make the relationship between a label and its respective point clear, use a connector. Set the connector's visibility and appearance options using the connector object.
