IPPSpeedometerScale.OuterRadius

Syntax

OuterRadius: IGxSizeF;

Description

The OuterRadius property determines an area of scale rendering relative to its center.

Comments

The range of available values: [0,1]. The smaller is the value, the closer is the scale to the center.

Example

Executing the example requires that the repository contains a database with the ADHOC identifier. A dashboard must contain a speedometer.

Add links to the Adhoc, Drawing, Express, Metabase, Speedometer system assemblies.

Sub UserProc;
Var
    Speedometer: IPPSpeedometer;
    MB: IMetabase;
    AdhocReport: IAdhocReport;
    EaxSpeedometer: IEaxSpeedometer;
    Enalyzer: IEaxAnalyzer;
    DsObjs: IAdhocDataSourceObjects;
    Scales: IPPSpeedometerScales;
    Scale: IPPSpeedometerScale;
Begin
    MB := MetabaseClass.Active;
    // Get dashboard
    AdhocReport := MB.ItemById("ADHOC").Edit As IAdhocReport;
    // Get dashboard data sources
    DsObjs := AdhocReport.DataSourceObjects;
    // Get speedometer
    Enalyzer := DsObjs.Item(0).GetSourceObject As IEaxAnalyzer;
    EaxSpeedometer := Enalyzer.Speedometer;
    // Get speedometer parameters
    Speedometer := EaxSpeedometer.Speedometer;
    // Get collection of speedometer scales
    Scales := Speedometer.Scales;
    // Get data scale
    Scale := Scales.DataScale;
    // Change slope angle of scale start
    Scale.StartAngle := 45;
    // Change placement step for additional markers
    Scale.Step_ := 2000;
    // Change scale rendering area
    Scale.OuterRadius.Height := 0.6;
    Scale.OuterRadius.Width := 0.7;
    // Display coordinates of scale center
    Debug.Writeline("Scale center coordinates: " + Scale.CenterPosition.X.ToString +
        ":" + Scale.CenterPosition.Y.ToString);
    // Display tooltip text
    Debug.Writeline("Tooltip text: " + Scale.ToolTip);
    (Enalyzer As IMetabaseObject).Save;
End Sub UserProc;

After executing the example scale rendering area, placement step for additional markers, scale slope angle are changed. The console window displays coordinates of scale center and tooltip text.
