IVZColorLegendBase.Scale

Executing the example requires that the repository contains an express report with the EXP identifier. The unit containing the example should have links to the Express, Metabase and Visualizators system assemblies. The specified procedure should be called from the Main entry point.

Before executing the example, the color scale of bubble tree looks as shown on the IVZColorLegendBase interface description page. Set two elements for this scale:

Sub UserProc;
Var
    Metabase: IMetabase;
    Analyzer: IEaxAnalyzer;
    BubbleTree: IVZBubbleTree;
    ColorLegend: IVZColorLegendBase;
    Scale: IVZDataScale;
Begin
    // Get the current repository
    Metabase := MetabaseClass.Active;
    // Get express report
    Analyzer := Metabase.ItemById("EXP").Edit As IEaxAnalyzer;
    // Get bubble tree
    BubbleTree := Analyzer.BubbleTree.BubbleTree;
    // Get color legend of bubble tree
    ColorLegend := BubbleTree.Legends.Item(0) As IVZColorLegendBase;
    // Disable displaying of the No Data element
    ColorLegend.NoDataVisible := False;
    // Get color legend scale
    Scale := ColorLegend.Scale;
    // Determine the number of elements equal to two
    Scale.ItemsCount := 2;
    // Save changes, made in express report
    (Analyzer As IMetabaseObject).Save;
End Sub UserProc;

After executing the example the number of scale elements that is equal to two is set for bubble tree color legend, and displaying of the No Data element is also disabled:
