IVZMapChartLayer.Bubbles

Syntax

Bubbles: IVZBubblesArray;

Description

The Bubbles property determines an array of bubble indicators for the map layer.

Comments

Bubble indicator enables the user to display additional information about territories, for example, correlation of indicator values.

To enable this type of indicators, use the registry setting: [HKEY_CURRENT_USER\Software\Foresight\Prognoz\10.0\Visualizers\MapChart\EnableBubbleIndicator] = 1. If the MapChart end section and the REG_DWORD parameter EnableBubbleIndicator =1 are missing in the registry, create them manually.

Working with bubble indicators is executed similarly as with pie indicators.

The example of map with bubble indicators:

Example

Executing the example requires that the repository contains an express report with the EXPRESS identifier with a map. Facts dimension has the 10124 key.

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

Sub UserProc;
Var
    MB: IMetabase;
    Express: IEaxAnalyzer;
    Map: IVZMapChart;
    Facts: IDimInstance;
    Slice: IEaxDataAreaSlice;
    Sel: IDimSelection;
    Layer: IVZMapChartLayer;
    BubblesArray: IVZBubblesArray;
    Bubble: IVZMapChartBubble;
Begin
    // Get repository
    MB := MetabaseClass.Active;
    // Get express report
    Express := MB.ItemById("EXPRESS").Edit As IEaxAnalyzer;
    // Get map
    Map := Express.MapChart.MapChart;
    // Set facts dimension as a metrics dimension
    Facts := Express.Pivot.Dimensions.FindByKey(10124).DimInstance;
    Slice := Express.DataArea.Slices.Item(0);
    Slice.IndicatorsDimension := Facts;
    // Enable the Bubble Color metric type and add all elements to selection
    Sel := Express.MapChart.IndicatorSelection(EaxMapChartIndicators.BubbleColor);
    Sel.SelectAll;
    // Get map layer
    Layer := Map.RootLayer.SubLayers.Item(0);
    // Get collection of bubble indicators
    BubblesArray := Layer.Bubbles;
    // Get an object for working with bubble indicators
    Bubble := BubblesArray.Item(0);
    // Change minimum radius of bubble indicators
    Bubble.LeastSizeRadius := 15.0;
    // Clear collection of bubble indicators
    BubblesArray.Clear;
    // Add the previously obtained object for working with bubble indicators
    BubblesArray.Add(Bubble);
    // Refresh and save report
    Express.RefreshAll;
    (Express As IMetabaseObject).Save;
End Sub UserProc;

After executing the example, bubble indicators are displayed on the express report map. The minimum radius 15 will be set for bubble indicators.
