A gauge is a dashboard
indicator (also known as a KPI) that displays the status or measure
of a variable or variables in relation to a target, goal, or interval.
Gauges are designed to achieve this goal in a way that is familiar
to users. Many real-life objects use gauges, such as cars and machines.
Gauges can be used to display a quantity, range, variable, or status.
They often appear in business intelligence dashboards.
Qualitative ranges are
required for all gauges in the designer. You can populate the range
intervals manually, or you can have them generated for you based on
the range of the actual data.
Gauges in the designer
support high cardinality.
