The Surface graph or series is used to represent a set of three-dimensional data as a mesh surface. It has three mandatory
series components, Position,
Depth and Value. The data in the Position and Depth
components must form a 2D rectangular grid on the xz
plane. The elevations of the mesh cells are determined by the data in the Value
component. The series also has an optional series component called LabelMember
whose data may be used as the mark labels for the mesh cells.
If the UseGradient property is set to true, the mesh cells will be
colored using a color gradient according to its elevation value in the Value
component. The color gradient is formed using the start, middle, and
end colors that are determined by the StartColor, MidColor,
and EndColor properties, respectively.
If the UsePalette property is set to true, the mesh cells will be
colored using a predefined color palette that is specified by the PaletteStyle
If both the UseGradient and the UsePalette properties are set
to false, the mesh cells will be colored using the color specified by Brush
