Add links to the Express and Chart system assembles.

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

Sub Button1OnClick(Sender: Object; Args: IMouseEventArgs);
Var
    Eax: IEaxAnalyzer;
    Chart: IChart;
    Series: IChartSeries;
    Arr: Array Of Variant;
Begin
    Eax := UiErAnalyzer1.ErAnalyzer;
    Chart := Eax.Chart.Chart;
    Arr := New Variant[2];
    Series := Chart.Series;
    Arr[0] := Series.Item(0).SeriePoint(0);
    Arr[1] := Series.Item(1).SeriePoint(0);
    Eax.KeepOnlyChartElements(Arr);
    Debug.WriteLine(Series.Count.ToString);
End Sub Button1OnClick;

Clicking the button keeps available only first points of two specified rows on the chart.
