The Dashboard allows you to use any data aware dashboard item as a filter for other dashboard items (Master Filter). To learn more about filtering concepts common to all dashboard items, see the Master Filtering topic.
When master filtering is enabled, you can click a gauge (or multiple gauges by holding down the CTRL key) to make other dashboard items only display data related to the selected gauge(s).
To learn how to enable master filtering in the Designer, see the Master Filtering topic.
To reset filtering, use the Clear Master Filter button (the 
icon) in the caption of the Gauge dashboard item, or the Clear Master Filter command in the Gauge’s context menu.
