Surface (Data Set)
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.
Parameterization
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 parameters of the 3D surface, computed using the average normal and by choosing the 2D axes using a set of geometrical rules.
•
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.
Advanced
Select the Define variables check box to create space variables for the surface. If needed, change the names of the space variables in the x and y fields.
