Description

The Chart property returns an object of the IChart type with the specified index, to which the legend element belongs.

Fore Example

Executing the example requires a regular report with the Report identifier.The report includes the following objects: a chart and an external legend.

Sub Main;
Var
    mb: IMetabase;
    rep: IPrxReport;
    legend: IPrxChartLegend;
    chartlegend: IChartExternLegend;
    objects: ITabObjects;
    C: IChart;
Begin
    mb := MetabaseClass.Active;
    rep := mb.ItemById("OBJ42859").Edit As IPrxReport;
    objects := (rep.ActiveSheet As IprxTable).TabSheet.Objects;
    legend := objects.Item(1).Extension As IPrxChartLegend;
    chartlegend := legend As IChartExternLegend;
    chartlegend.AddChart(objects.Item(2).Extension As IChart);
    C:= chartlegend.Chart(0);
    debug.WriteLine(chartlegend.isDirty);
    If chartlegend.ChartCount > 0 Then
        chartlegend.RemoveChart(chartlegend.Chart(0));
    End If;
    chartlegend.ItemSeparator:= "||";
    (rep As IMetabaseObject).Save;
End Sub Main;

After executing the example the C variable contains an object of the IChart type with the specified index, to which the legend element belongs.
