Report Data View Properties: Value
A Report Value view is used to display a gauge in a Report Container. The data displayed in the gauge is provided by a Report Data Source of query type.
The gauge report shows the query result value against the number of concerned occurrences in the repository.
Characteristics 
The Characteristics page includes the following properties:
Sharing:
"Public" (default): the Report Value View can be reused in several reports. The Report Value view is available at Report Template or Report Chapter creation.
"Private": the Report Value View cannot be reused.
Data Source shows the query (without parameters) from which the Report Value View is built.
Display shows the renderer type applied to the Tree view.
Value: Graphic.
Chart Type shows the chart type.
Value: Gauge Chart.
Chart 
The Chart page defines how the gauge is built and customized:
Value defines the gauge value, i.e. the (Data Source) query on which the chart is based.
Value Computation defines the value computation mode. For example, it can be more efficient to perform a computation relating to a minimum value or to a maximum value.
Values: Default, Added to min, subtracted from max.
Min value defines the gauge minimum value. By default this minimum value is 0. You can define a query that sets the gauge minimum value.
Values: a query of the same source, or empty (in that case 0).
Max value defines the maximum value of the gauge. By default this maximum value is the number of occurrences of the object type that represents the gauge. You can define a query that sets the gauge maximum value.
Values: a query of the same source, or empty (in that case the maximum number of occurrences concerned).
Drill-down defines whether a drill-down is available on the gauge or not.
Values: yes, no
Specific Drill-down defines the occurrences displayed in the drill-down. By default all the occurrences are displayed. This parameter enables to select another query (than the Data Source query) for the drill-down.
Value: a query of the same source, or empty (in that case the Data Source query is used).
_Settings automatically fed (and updated) while setting the chart parameters.
