ILanerCalculateSerie.Calculate

Syntax

Calculate;

Description

The Calculate method calculates the calculated series.

Example

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 working area of a time series database, which data table has more than one data series, should be loaded to UiErAnalyzer1.

The example is a handler of the OnClick event for the Button1 component.

    Det.Expression.AsString := Term1.TermToInnerText + " + " + Term2.TermToInnerText;
    NewSerie.Calculate;
    Laner.EndUpdate;
End Sub Button1OnClick;

After executing the example the new calculated series which is the sum of the two first series data is added.
