Fore Syntax

Font: IGxFont;

Fore.NET Syntax

Font: Prognoz.Platform.Interop.Drawing.GxFont;

Description

The Font property determines a text font.

Comments

To determine a font color, use the IBubbleChartPlacedItem.FontColor property.

Fore Example

Executing the example requires an express report with the Express_Font identifier. The express report is set up 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;
    // bubble chart caption parameters;
    BubbleCaption := Bubble.Caption;
    // display 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 bubble chart component border:
    BubbleCaption.Padding := 20;
    // values of margins:
    BubbleCaption.Margin := New GxRectF.Create(0, 0, 0, 20);
    // text wrap:
    BubbleCaption.WordWrap := True;
    // caption text:
    BubbleCaptionText := Bubble.Caption;
    BubbleCaptionText.Text := "Dynamics of change";
    (Eax As IMetabaseObject).Save;
End Sub UserProc;

After executing the example the following parameters are determined for the bubble chart caption:

The caption is displayed.
Caption text font: Arial.
Font size - 14.
Font color: red.
Value of margins- 20 pixels.
Text direction - bottom to top.
Horizontal caption alignment - to the right edge.
Vertical caption alignment - center.
Word wrap in the caption text is enabled.
