IPrxMapDataAdapter.Attribute

Syntax

Attribute: String;

Description

The Attribute property determines attribute of the map layer.

Example

Executing the example requires a regular report with the REGULAR_REPORT identifier, the report active page contains a map with the Regions layer. A cube containing the Territories dimension is added to the list of report data sources. Add links to the Metabase, Report, Tab, Map, Dimensions system assemblies.

Sub UserProc;
Var
    Mb: IMetabase;
    MObj: IMetabaseObject;
    Report: IPrxReport;
    Tab: ITabSheet;
    Map: IMap;
    BarVisual: IMapBarVisual;
    PrxDA: IPrxMapDataAdapter;
    Slice: IPrxSlice;
    MapDAdapt: IPrxMapDataAdapter;
    i, j: Integer;
Begin
    Mb := MetabaseClass.Active;
    MObj := Mb.ItemById("REGULAR_REPORT").Edit;
    Report := MObj As IPrxReport;
    Tab := (Report.ActiveSheet As IPrxTable).TabSheet;
    Map := Tab.Objects.Item(1).Extension As IMap;
    BarVisual := Map.Layers.FindByName("Regions").Visuals.AddBarVisual;
    Slice := Report.DataSources.Item(0).Slices.Item(0);
    PrxDA := Slice.CreateMapDataAdapter(PrxMapAdapter.Dynamic);
    PrxDA.Dimension := Slice.Dimensions.FindByName("Territories").Dimension.Dimension;
    PrxDa.Index := PrxDA.Dimension.Indexes.PrimaryIndex;
    PrxDA.Attribute := "ID";
    BarVisual.DataAdapter := PrxDA As IMapDynamicDataAdapter;
    PrxDA.Expression.AsString := "AT[Id]+" + Char.Chr(34) + ")" + Char.Chr(34) + "+AT[Name]";
    PrxDa.Expression2.AsString := "VALUE";
    Map.Layers.FindByName("Regions").TerritoryInfoAdapter := PrxDa;
    MObj.Save;
End Sub UserProc;

After executing the example a bar indicator is created for the Regions map layer, and the custom label format for names and identifiers is set in the map layer territory info.
