This event is emitted after _any_ change to dashboard filters (be it date or attribute filter). The event describes the new state of the entire filter context.
export interface DashboardFilterContextChanged extends IDashboardEvent
This event is emitted as convenience - more granular events describe all the possible changes to the dashboard filters and can be used to event source the state of filter context.
See also filterContextToDashboardFiltersByWidget() and filterContextToDashboardFiltersByDateDataSet() convertors – those allow you to convert the
filterContext in the event payload to array of IFilter instances you can use with visualizations, filter UI components and so on.
