ObservationValue(Attribute: IMetaAtribute; Date: DateTime): Variant;
Attribute. Indicator observation attribute.
Date. Calendar point.
The ObservationValue property determines observation attribute value of an indicator in defined calendar point.
Executing the example requires a form with the following components: the Button component named Button1, the TabSheetBox component named TabSheetBox1, and the UiErAnalyzer component named UiErAnalyzer1. UiErAnalyzer1 is a data source for TabSheetBox1. A workbook of the time series database should be loaded to UiErAnalyzer1.
The example is a handler of the OnClick event for the Button1 component.
Add links to the Cubes, Express, ExtCtrls, Forms, Laner, Rds, and Tab system assemblies.
Sub Button1OnClick(Sender: Object; Args: IMouseEventArgs);
Var
ErA: IEaxAnalyzer;
Laner: ILaner;
Series: ILanerSeries;
Serie: ILanerSerie;
Rubricator: IRubricator;
ObsAttr: IMetaAttributes;
attr: IMetaAttribute;
dt: DateTime;
Begin
ErA := UiErAnalyzer1.ErAnalyzer;
Laner := ErA.Laner;
Series := Laner.Series;
Serie := Series.Item(0);
Rubricator := Laner.RubricatorInstance.Rubricator;
ObsAttr := Rubricator.Values.Attributes;
attr := ObsAttr.FindByKind(MetaAttributeKind.Value);
dt := DateTime.ComposeDay(2006, 1, 1);
Debug.WriteLine(Serie.ObservationValue(attr, dt));
End Sub Button1OnClick;
After executing the example the console window displays the value of the workbook first series for the 1st of January 2006.
