When defining a 3D Chart label, specify how and where to attach it to the chart.

The attachment method determines the basic appearance of the Chart3DLabel. The best method depends on what the Chart3DLabel is used for. C1Chart3D includes the following types of attachment methods:

• Coordinates attaches the label outside the PlotCube and it can appear anywhere on the chart. The number of pixels from the top-left corner of the chart to the center of the Chart3DLabel can be specified. When attached this way, customizing the facing plane and cube font has no effect.
• DataCoordinates attaches the label inside the PlotCube to any point in 3D space within the data range. Specify the data X, Y, and Z-coordinates. The ChartLabels must fall within the maximum and minimum data coordinates for the axes, otherwise the label is not drawn.
• DataIndex attaches the label inside the PlotCube to a specific data point on the chart. Specify the row and column indices.

The following chart illustrates the attachment methods:

Use the AttachMethod of the Chart3DLabel property to set the attachment method, and the properties of Chart3DAttachMethodData class to set the attachment point. At design time, these properties are located under AttachMethodData node in the Chart3DLabel Collection Editor.
