Class Labels<T extends Labels>

java.lang.Object
  org.moxieapps.gwt.highcharts.client.Configurable<T>
      org.moxieapps.gwt.highcharts.client.labels.Labels<T>

Direct Known Subclasses:

BaseDataLabels, StackLabels, XAxisLabels, YAxisLabels

public abstract class Labels<T extends Labels>
extends Configurable<T>

Represents the common base class for all label configuration option types, which allows for general options to be set via the inherited Configurable.setOption(String, Object) method. But also exposes type specific methods that the caller is encouraged to use instead, such as setAlign(org.moxieapps.gwt.highcharts.client.labels.Labels.Align), setColor(String), etc.

Note that this class is abstract and therefore can't be instantiated directly. Instead you should create an instance of more specific sub type, such as XAxisLabels, YAxisLabels, or DataLabels.
