The Dashboard Designer provides the capability to create calculated fields that allow you to apply complex expressions to data fields that are obtained from the dashboard's data source. You can use these fields in data visualizations as regular data source fields.

Creating a Calculated Field

After you have created a data source, you can add a new calculated field based on the existing data source fields.

To create a calculated field, select the required data source (and the required query/data member, if applicable) in the Data Source Browser and click the Add Calculated Field button in the Ribbon's Data Source tab...

...or right-click the Field List and select Add Calculated Field in the context menu.

This invokes the Expression Editor dialog, which allows you to specify an expression that will be used to obtain calculated field values. Here, you can construct the required expression.

You can use the following elements in expressions.

•Functions

Note

To learn how to use Aggregate functions, see Aggregations. The Expression Operators, Functions and Constants topic lists the functions (DateTime, Math, String, etc.) supported by expressions.

•Operators

•Columns

•Constants

After the expression has been specified, click OK. This displays a new calculated field in the data source structure.

Now you can specify the required calculated field type, change its default name, etc.
