Add(Value: IPPSpeedometerSector): Integer;
Value. Added sector.
The Add method adds a sector to the collection.
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.

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 scale sectors
Sectors := Scale.Sectors;
// Display size of sectors collection
Debug.WriteLine("Sectors before removal: " + Sectors.Count.ToString);
// Clear collection of sectors
Sectors.RemoveAll;
// Create a new sector
Sector := New PPSpeedometerSector.Create;
// Set sector start and end values
Sector.StartValue := 15000;
Sector.EndValue := 20000;
// Set sector start and end width
Sector.StartSize := 20;
Sector.EndSize := 60;
// Determine offset measurement unit - percents
Scale.IsAbsoluteSectorOffset := False;
// Set sector offset
Sector.Offset := 0.1;
// Set up sector background fill color
Sector.EnableBrush := True;
Color := New GxColor.CreateRGB(0,255,0);
SolidBrush := New GxSolidBrush.Create(Color);
Sector.Background := SolidBrush;
// Add a new sector to collection
Sectors.Add(Sector);
(Enalyzer As IMetabaseObject).Save;
End Sub UserProc;
After executing the example the console window displays the size of the sectors collection. The sectors collection is cleared, after which a new sector is created, set up and added to the collection.
