You can change the default position of the MarkedZone's label by either choosing from an enum of predefined positions: chartMarkedZone.Label.Appearance.Position.AlignedPosition
or by turning off the chartMarkedZone.Label.Appearance.Position.Auto
property and providing X and Y coordinates for it. Have in mind that these are physical coordinates and not the coordinates of the PlotArea.
