IPPSpeedometerLabels.Count

Syntax

Count: Integer;

Description

The Count property returns the size of the text labels collection.

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;
    Labels: IPPSpeedometerLabels;
    Color: IGxColor;
    Font: IGxFont;
    i: Integer;
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;
    // Get collection of text labels of data scale
    Labels := Scale.Labels;
    // Output collection elements
    For i := 0 To Labels.Count - 1 Do
        Debug.WriteLine(Labels.Item(i).Text);
    End For;
    // Add a text label
    Labels.Add("New label");
    // Set up font size of the text displayed in text labels
    Font := New GxFont.Create("Arial",12);
    Labels.Font := Font;
    // Set up text color
    Color := New GxColor.CreateRGB(0,255,255);
    Labels.FontColor := Color;
    (Enalyzer As IMetabaseObject).Save;
End Sub UserProc;

After executing the example the console window displays the text located in text labels of data scale. A new text label is added. Text font and color are set up for all text labels.
