    chartlegend: IChartExternLegend;
    items: IChartExternLegendItems;
    item: IChartExternLegendItem;
Begin
    mb := MetabaseClass.Active;
    rep := mb.ItemById("OBJ12399").Open(Null) As IPrxReport;
    legend := (rep.ActiveSheet As IprxTable).TabSheet.Objects.Item(2).Extension As IPrxChartLegend;
    chartlegend := legend As IChartExternLegend;
    items := chartlegend.InternalItems;
    item := Items.Item(0);
    sizef := New GxSizeF.Create(12, 12);
