BigImage: IVZResourceImage;
The BigImage property determines an icon for size legend maximum value.
Executing the example requires that the repository contains an express report with the EXPRESS identifier. A data source and the Bubble Tree visualizer should be selected in express report to display data.
Add links to the Express, Metabase, Visualizators system assemblies.
Sub UserProc;
Var
Metabase: IMetabase;
Analyzer: IEaxAnalyzer;
BubbleTree: IVZBubbleTree;
SizeLegend: IVZSizeLegend;
LegendMarker: IVZSizeLegendMarker;
BigImage, SmallImage: IVZResourceImage;
Begin
// Get the current repository
Metabase := MetabaseClass.Active;
// Get express report
Analyzer := Metabase.ItemById("EXPRESS").Edit As IEaxAnalyzer;
// Get bubble tree
BubbleTree := Analyzer.BubbleTree.BubbleTree;
// Get size legend
SizeLegend := BubbleTree.Legends.Item(1) As IVZSizeLegend;
// Get legend markers
LegendMarker := SizeLegend.Marker;
// Set markers
LegendMarker.BigImage := New VZResourceImage.Create;
LegendMarker.SmallImage := New VZResourceImage.Create;
LegendMarker.Marker := VisualizatorSizeMarkerShape.Custom;
// Set icon for maximum value
BigImage := LegendMarker.BigImage;
BigImage.ResourceId := VisualizersResourceId.SizeLegendArrowBig;
// Set icon for minimum value
SmallImage := LegendMarker.SmallImage;
SmallImage.ResourceId := VisualizersResourceId.SizeLegendCubeSmall;
// Save changes in express report
(Analyzer As IMetabaseObject).Save;
End Sub UserProc;
After executing the example, bubble tree size legend icons are changed in the express report:
