Methods

Method	Modifiers	Description
setDataSupport(support)		Tells Grafana if the plugin should subscribe to annotation and alertState results.
setDefaults(defaults)
setEditor(editor)
setMigrationHandler(handler)		This function is called before the panel first loads if the current version is different than the version that was saved.This is a good place to support any changes to the options model
setNoPadding()
setPanelChangeHandler(handler)		This function is called when the visualization was changed. This passes in the panel model for previous visualisation options inspection and panel model updates.This is useful for supporting PanelModel API updates when changing between Angular and React panels.
setPanelOptions(builder)		Enables panel options editor creation
useFieldConfig(config)		Allows specifying which standard field config options panel should use and defining default values
