Count: Integer;
The Count property determines the number of colors in the collection.
Executing the example requires a regular report with the REPORT identifier with a map on the report sheet.
Add links to the Drawing, Map, Metabase, Report, and Tab system assemblies.
Sub UserProc;
Var
Metabase : IMetabase;
MetabaseObject: IMetabaseObject;
Report: IPrxReport;
Sheets: IPrxSheets;
SheetT : IPrxTable;
Map : IMap;
BarVisual : IMapBarVisual;
Collection : IMapColorCollection;
Begin
Metabase := MetabaseClass.Active;
MetabaseObject := Metabase.ItemById("REPORT").Edit;
Report := MetabaseObject As IPrxReport;
Sheets := PrxReport.ActiveReport.Sheets;
SheetT := Sheets.Item(0) As IPrxTable;
Map := SheetT.TabSheet.Objects.Item(0).Extension As IMap;
BarVisual := Map.Layers.FindByName("Regions").Visuals.Item(0) As IMapBarVisual;
Collection := BarVisual.Color.Values;
Collection.Count := 2;
Collection.Item(0) := GxColor.FromName("Red");
Collection.Item(1) := GxColor.FromName("Blue");
MetabaseObject.Save;
End Sub UserProc;
After executing the example the specified set of colors is determined for the bar indicator fill.
