IEaxAnalyzer.ExcludeChartElements

Fore Syntax

ExcludeChartElements(Elements: Array);

Fore.NET Syntax

ExcludeChartElements(Elements: System.Array);

Parameters

Elements. Array containing chart elements to be excluded.

Description

The ExcludeChartElements method excludes from selection specified dimensions elements.

Comments

Array which is set in the Elements parameter can contain series or points of chart. On method executing, dimension elements corresponding to selected chart elements will be excluded from selection.

Fore Example

Executing the example requires a form containing the Button component named Button1, the UiErAnalyzer component named UiErAnalyzer1 which is a data source for the ChartBox component named ChartBox1. Chart of the express report specified as data source for UiErAnalyzer1 should contain at least two series. Set for the UiErAnalyzer1 component the Active property = True.

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);
    Arr[1] := Series.Item(1);
    Eax.ExcludeChartElements(Arr);
End Sub Button1OnClick;

On button clicking the first two chart series are removed.

Fore.NET Example

The requirements and result of the Fore.NET Example execution match with those in the Fore Example. Use Fore.NET analogs instead of Fore components.
