IVZMapChartPie.UseInvertedAngles

Syntax

UseInvertedAngles: Boolean;

Description

The UseInvertedAngles property determines whether sectors are displayed pie indicator reversely on the map.

Comments

Available values:

True. Sectors are displayed reversely.
False. Default. Sectors are not displayed reversely.

For example:

Example

Executing the example requires that the repository contains an express report with the EXPRESS_REPORT identifier. The report contains a map. The map displays pie indicators and two arrows that go from one area. To display pie indicators on a map:

Select the Pie radio button in the Facts.
Select the Value and Dimension elements.

To work with arrows, study requirements for showing arrows.

Add links to the Express, Metabase, Visualizators system assemblies.

Sub UserProc;
Var
    Metabase: IMetabase;
    EaxAnalyzer: IEaxAnalyzer;
    EMap: IVZMapChart;
    MapPie: IVZMapChartPie;
Begin
    // Get metabase object
    Metabase := MetabaseClass.Active;
    // Get express report
    EaxAnalyzer := Metabase.ItemById("EXPRESS_REPORT").Edit As IEaxAnalyzer;
    // Get express report map as a visualizer
    EMap := EaxAnalyzer.MapChart.MapChart;
    // Determine map arrow highlighting mode by source territory
    EMap.ArrowEffectsMode := MapChartArrowEffectsMode.StartShape;
    // Get pie indicator
    MapPie := EMap.RootLayer.SubLayers.Item(0).Pies.Item(0);
    // If indicator visibility is disabled, then enable it
    If Not MapPie.Visible Then
        MapPie.Visible := True;
    End If;
    // Display indicator angles reversely
    MapPie.UseInvertedAngles := True;
    // Set minimum angle of indicator sectors
    MapPie.LeastAnglePart := 150;
    // Save changes
    (EaxAnalyzer As IMetabaseObject).Save;
End Sub UserProc;

After executing the example the minimum angle of indicator sectors is changed, sectors are displayed reversely, highlighting mode by source territory is set for arrows (all the arrows that go from the moused over area are highlighted).
