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 should be loaded to UiErAnalyzer1. Displaying of several additional attributes should be set up for working area series.

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

Add links to the Express, ExtCtrls, Forms, Laner, and Tab system assemblies.

Sub Button1OnClick(Sender: Object; Args: IMouseEventArgs);
Var
    ErAn: IEaxAnalyzer;
    Laner: ILaner;
    LanerAttr: ILanerAttributeColumns;
Begin
    ErAn := UiErAnalyzer1.ErAnalyzer;
    Laner := ErAn.Laner;
    Laner.BeginUpdate;
    LanerAttr := Laner.AttributeColumns;
    LanerAttr.Remove(0);
    Laner.EndUpdate;
End Sub Button1OnClick;

After executing the example, the first element is deleted from the collection of displayed attributes.
