A Chart3DLabel is an independent label that can be displayed inside or outside the PlotCube. ChartLabels are used to highlight an important data point, but can also be used generally to provide information on data or on the chart.

There is no limit to the number of ChartLabels a chart can contain. Each Chart3DLabel has a foreground and background color, border, fonts, and attachment attributes that can be customized.

The Chart3DLabel object provides a number of properties that help define and position the chart label. The most important of these properties are the following:

• The Text property specifies the text to appear in the chart label, and is of type Label.
• The View3D property specifies the position of the chart label in 3D space. The position is specified as LabelView3DEnum.
• The Connected property is a Boolean that specifies whether a line is to be drawn from the chart label to its attached location. If True, the line is drawn.

The following code sets the above properties:

  .View3D = LabelView3DEnum.YZ
  .Connected = True
End With

Chart3DLabel lab = C1Chart3D1.ChartLabels[1];
lab.Text = "Here is my chart label";
lab.View3D = LabelView3DEnum.YZ;
lab.Connected = true;
