IVZMapChartPie.StartAngle

Syntax

StartAngle: Double;

Description

The StartAngle property determines an angle of rotation of pie indicator on the map counter-clockwise.

Comments

The property is set to 0 by default.

Example

Executing the example requires that the repository contains an express report with the EXPRESS identifier containing a map with pie indicators.

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

Sub UserProc;
Var
    MB: IMetabase;
    Express: IEaxAnalyzer;
    Map: IVZMapChart;
    Layer: IVZMapChartLayer;
    PiesArray: IVZPiesArray;
    Pie: IVZMapChartPie;
Begin
    // Get repository
    MB := MetabaseClass.Active;
    // Get express report
    Express := MB.ItemById("Bars2_copy1").Edit As IEaxAnalyzer;
    // Get map
    Map := Express.MapChart.MapChart;
    // Get map layer
    Layer := Map.RootLayer.SubLayers.Item(0);
    // Get collection of pie indicators on the layer
    PiesArray := Layer.Pies;
    // Get object for working with pie indicators
    Pie := PiesArray.Item(0);
    // Set angle of rotation of pie indicators counter-clockwise
    Pie.StartAngle := 90.0;
    // Set width of pie indicator borders
    Pie.BorderThickness := 2.0;
    // Set minimum value of pie indicator borders
    Pie.LeastRadiusPart := 15.0;
    // Set maximum number of sectors in pie indicators
    Pie.MaxPiesCount := 2;
    // Clear the collection of pie indicators
    PiesArray.Clear;
    // Add previously obtained object for working with pie indicators
    PiesArray.Add(Pie);
    // Refresh and save report
    Express.RefreshAll;
    (Express As IMetabaseObject).Save;
End Sub UserProc;

After executing the example, the settings are determined for pie indicators on the express report map:

Angle of rotation of pie indicators - 90 degrees counter-clockwise.
Width of pie indicator borders - 2.
Minimum value of pie indicator radius - 15.
Maximum number of sectors in pie indicators - 2.
