IVZDataScale.InactiveItem

Syntax

InactiveItem: Variant;

Description

The InactiveItem property determines settings for inactive visualizer elements.

Comments

As the property value determine the brush described with the IGxBrush interface or numeric value depending on the scale type.

Visualizer element is considered inactive if it belongs to the interval that is not selected for displaying in the legend.

Example

Executing the example requires that the repository contains an express report with the EXPRESS_REPORT identifier that contains bubble tree. The color scheme of bubble tree looks as on the IVZDataScale interface description page. Set new colors for scale elements.

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

Sub UserProc;
Var
    Metabase: IMetabase; // Repository
    EaxAnalyzer: IEaxAnalyzer; // Express report
    BubbleTree: IVZBubbleTree; // Bubble tree
    Scale: IVZDataScale; // Color scale
    Color: IGxColor; // Color
    ColorLegend: IVZColorLegendBase; // Color legend
Begin
    // Get repository object
    Metabase := MetabaseClass.Active;
    // Get express report object
    EaxAnalyzer := Metabase.ItemById("EXPRESS_REPORT").Edit As IEaxAnalyzer;
    // Get bubble tree
    BubbleTree := EaxAnalyzer.BubbleTree.BubbleTree;
    // Get bubble tree color scale
    Scale := BubbleTree.ColorVisual.ColorMapping.Scale;
    // Create purple color
    Color := New GxColor.CreateRGB(102, 0, 204);
    // Determine this color for legend element bubbles
    Scale.InactiveItem := New GxSolidBrush.Create(Color);
    // Set the color of bubbles from the second legend interval
    Scale.IsInactiveItem(1) := True;
    // Create olive color
    Color := New GxColor.CreateRGB(128, 128, 0);
    // Determine brush for the No Data legend element
    Scale.NoData := New GxSolidBrush.Create(Color);
    // Get legend
    ColorLegend := BubbleTree.Legends.Item(0) As IVZColorLegendBase;
    // Enable highlighting of legend elements
    ColorLegend.DoHighlight := True;
    // Create a mustard color
    Color := New GxColor.CreateRGB(205, 205, 0);
    ColorLegend.HighlightBrush := New GxSolidBrush.Create(Color);
    // Set legend element selection on mouse click
    ColorLegend.HoverMode := VisualizatorHoverMode.Click;
    // Save changes to the express report
    (EaxAnalyzer As IMetabaseObject).Save;
End Sub UserProc;

After executing the example:

Purple color of bubbles will be set on selecting elements from from the second legend interval.
Olive color is set for the No Data legend element.
Mustard color is set for highlighting of active legend intervals.
