AddSelectionSet(SelSet: IDimSelectionSet; Type: CubeDataType);
AddSelectionSet(SelSet: Prognoz.Platform.Interop.Dimensions.IDimSelectionSet; Type: CubeDataType);
SelSet. Selection according to which cells are taken.
Type. The method of data creation that is to be set for the cell.
The AddSelectionSet method sets how data is generated for multiple cells that match the specified selection.
Executing the example requires a standard cube with the STD_CUBE identifier. The cube contains two dimensions and facts dimension. The aggregation for calendar dimension with the CALENDAR identifier is set up.
Add links to the Cubes, Dimensions, Matrix and Metabase system assemblies. In Fore.NET add a link to the ForeSystem assembly.

On executing the example the cube output matrix is calculated. The development environment console displays information about matrix: values in cells and cells coordinates. The cells containing calculated data will be marked by the * character. After that, according to modified selection of the CALENDAR dimensions, data formatting method will be set for cells and information about matrix will be re-displayed to the development environment console.
