API

info

All widgets extend a third-party library component. See the extends property below for more information about the base component's API.

Extends	p-radiobutton
Angular Selector	provenance-radiobutton

Properties

Name	Type	Default	Required	Description
id	string	""	Yes	Unique identifier for the element. Used by ProvenanceWidgets for internal state management and visualizations.
data	any[]	undefined	Yes	An array of objects to display as radiobuttons. Each object must have a label and a value property. Alternatively, you can map your properties using label="your_label_property" and value="your_value_property".
selected	string		No	The selected value. It must be one of the values in the data array. Two-way binding is supported.
freeze	boolean	false	No	Whether to freeze the provenance. If true, the widget will not record any provenance, and interactions will not create/update any visualizations. NOTE: The widget does not update when the property is changed.
visualize	boolean	true	No	Whether to visualize the provenance. NOTE: The widget does not update when the property is changed.
provenance	Provenance	undefined	No	The provenance of interactions recorded by the widget. Use this property to persist, restore, modify, or reconstruct the provenance of interactions for the widget. To override the provenance, revalidate must be set to true. Two-way binding is supported.

Events

Name	EventEmitter<T>	Description
selectedChange	string	Emits the updated selected values when the radiobutton selection changes.
provenanceChange	<Provenance>	Emits the provenance when the radiobutton selection changes.
