An object defining the label configuration options.
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.
Formats the point argument before it is displayed in the point label. To format the point value, use the format option.

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.

Specifies the argument value of the represented point as it is set in the data source.
Specifies the argument value of the represented point. Differs from the originalArgument when the axis' argument type differs from the argument type in the data source. In this instance, argument has the type of the argument axis.
Specifies the argument value of the represented point with applied formatting if the argumentFormat property is specified.
- size (for bubble series only)
