    mb: IMetabase;
    rep: IPrxReport;
    chartlegend: IChartExternLegend;
    objects: ITabObjects;
    UnRed: IUndoRedo;    
Begin
    mb := MetabaseClass.Active;
    rep := mb.ItemById("Report").Edit As IPrxReport;
    objects := (rep.ActiveSheet As IprxTable).TabSheet.Objects;
    chartlegend := objects.Item(1) As IChartExternLegend;
    chartlegend.AddChart(objects.Item(2) As ichart);
    UnRed:=chartlegend.UndoRedo;
    UnRed.Enabled:= True;
    UnRed.Limit:= 50;
    (rep As IMetabaseObject).Save;
