Use a Surface () data set to visualize data on surfaces (boundaries) of a 3D geometry. Refer to this data set to plot and evaluate a value on a surface using a 2D plot group and a Surface or Contour plot, for example.
Specify how to parameterize the surface. Choose from one of these options in the x- and y-axes list to specify what the local x- and y-axes represent:
• Surface parameters (the default) uses the parameters of the 3D surface.
• xy-plane, yz-plane, zx-plane, yx-plane, zy-plane, and xz-plane are the local x- and y-axes representing the global xy-plane, yz-plane, zx-plane, yx-plane, zy-plane, and xz-plane, respectively.
• If Expression is selected, enter any expression, including the global spatial coordinates, for example, in the x-axis and y-axis fields. The default values are x and y, respectively.
