The Dashboard allows you to use any data aware dashboard item as a filter for other dashboard items. This feature is called Master Filtering.
To enable master filtering, go to the dashboard item's Interactivity menu and use the Master Filtering Mode option.
The Master Filter item supports the following modes.
To disable the Master Filter, select None as a Master Filter mode.
When different items in a dashboard are bound to different data sources, you can specify that a particular Master Filter should be applied across data sources. This means that it will apply filtering to fields with matching names in all data sources.
To filter data across data sources, enable the Cross-Data-Source Filtering in the dashboard item's Interactivity menu.
You can prevent specific dashboard items from being affected by Master Filters. To do this, enable the Ignore Master Filters option in the dashboard item's Interactivity menu.
