Reporting widgets are used in the Event and Global dashboards to quickly give you an overview of the existing data in your Azavista account.
They can be used, for example, to display the total number of objects at Global level (e.g. contacts, events, organizations) or to see participants organized by a specific field or the stage they're in.
Clicking on a specific sorting section of a widget will show you the Participant list with only the participants that are included in this section.
For example, when using a "Participants by stage" widget, clicking on the "Pre-arrival" part of the donut will display all the participants in the stage "Pre-arrival"
