Exempel

Följande kodexempel visar hur du lägger till en tröskelrad när diagramkontrollen har lagts till på designytan. Diagrammet använder en icke-återkommande bandlinje för att visa en beräkning av medelvärdet för alla datapunkter i en serie.

Kommentarer

När den här egenskapen är inställd på värdet Autoär texten orienterad baserat på diagramtypen. För alla X-Y-diagramtyper som inte är liggande, är X-axelns bandlinjetext vågrätt orienterad från vänster till höger längst ned på bandlinjen. För stapeldiagram är X-axelns bandlinjetext lodrätt orienterad uppifrån och ned till höger om bandlinjen.
