Example

Executing the example requires a form with the Button1 button on it, the UiErAnalyzer component named UiErAnalyzer1, and the ChartBox component, that displays chart of the express report, connected to the UiErAnalyzer1.

Sub Button1OnClick(Sender: Object; Args: IMouseEventArgs);
Var
    Expr: IEaxAnalyzer;
    Chart: IEaxChart;
Begin
    Expr := UiErAnalyzer1.Instance As IEaxAnalyzer;
    Chart := Expr.Chart;
    Chart.CorrectSerieIndex(0);
    If Chart.IsPointDrillable(0, 0, EaxDrilltype.Down) Then
        Chart.DrillPoint(0, 0, EaxDrilltype.Down, 0);
    End If;
End Sub Button1OnClick;

On clicking the button it is checked, whether data can be drilled down for the specified chart point. The drilldown is performed if available.
