Fore Example

Executing this example requires an express report with the Express_Font identifier. The express report is configured to ensure bubble chart displaying and operation.

Add links to the Metabase, Cubes, Dimensions system assemblies.

Sub UserProc;
Var
    MB: IMetabase;
    Eax: IEaxAnalyzer;
    Bubble: IBubbleChart;
    BubbleCaption: IBubbleChartPlacedItem;
    BubbleCaptionText: IBubbleChartCaption;
Begin
    MB := MetabaseClass.Active;
    Eax := MB.ItemById("Express_Font").Edit As IEaxAnalyzer;
    Bubble := Eax.BubbleChart.Chart;
    // parameters of bubble chart title;
    BubbleCaption := Bubble.Caption;
    // displaying of text:
    BubbleCaption.Visible := True;
    // text font:
    BubbleCaption.Font := New GxFont.Create("Arial", 14);
    // font color:
    BubbleCaption.FontColor := GxColor.FromName("Red");
    // text direction:
    BubbleCaption.TextDirection := BubbleChartTextDirection.BottomToTop;
    // vertical alignment of text:
    BubbleCaption.VerticalAlignment := ChartVerticalAlignment.Middle;
    // horizontal alignment of text:
    BubbleCaption.HorizontalAlignment := ChartHorizontalAlignment.Right;
    // value of padding from text to matrix component border:
    BubbleCaption.Padding := 20;
    // values of outer indents:
    BubbleCaption.Margin := New GxRectF.Create(0, 0, 0, 20);
    // text wrapping is available :
    BubbleCaption.WordWrap := True;
    // title text:
    BubbleCaptionText := Bubble.Caption;
    BubbleCaptionText.Text := "Dynamics of change";
    (Eax As IMetabaseObject).Save;
End Sub UserProc;

On executing this example the following parameters are defined for the bubble chart title:

Title is shown.
Title text font: Arial.
Font size - 14.
Font color: red.
Value of outer indents - 20 pixels.
Text direction - from bottom to top.
Horizontal title alignment: to the right edge.
Vertical title alignment: center.
Word wrapping in the title text is enabled.

Fore.NET Example

Requirements and the result of execution of the Fore.NET example are similar to the Fore example.
