Chart 3d add line 3D

Hi C1,
Can I draw a line 3D in my chart?
I use this code
Dim carea As Area = C1ChartBGM.ChartArea
carea.AxisY.AnnoMethod = AnnotationMethodEnum.Mixed
carea.AxisY.OnTop = False
Dim vl As ValueLabel = carea.AxisY.ValueLabels.AddNewLabel()
vl.GridLine = True

vl.Appearance = ValueLabelAppearanceEnum.ArrowMarker
vl.Moveable = False
vl.MarkerSize = 14
vl.Color = Color.DarkBlue
vl.NumericValue = Scheda.Dati(SchedaSelezionata).Raz.FabbRazione.ACCRESCIMENTO

but this code draw a line 2D (please see attached image).

Thanks

Andrea
