Table 21-7: Dataset Types.
Link	Description and Plot Use
Array 1D, Array 2D, and Array 3D	Create 1D, 2D, and 3D arrays of other datasets, so that you can plot the same data in multiple locations as an array of plots.

Isosurface (Dataset)	To visualize isosurfaces in 3D. Use this dataset to create arrow surface plots, surface plots, and contour plots. In addition, the contour dataset can be applied to the isosurface dataset.
Join	To join the solution data from two Solution datasets. This makes it possible to evaluate and plot the difference between two solutions, for example.
Kernel Density Estimation	To compute the kernel density estimation (KDE) from a table with data.
Layered Material	To create a volume/domain (3D) dataset for a layered shell physics defined using a surface/boundary (2D) geometry and a built-in extra dimension (1D) geometry. Use this dataset to plot or evaluate layered shell quantities on a domain level or its lower dimensions. Requires the AC/DC Module, Composite Materials Module, or Heat Transfer Module.
Maximum and Minimum	Creates a dataset that computes the maximum or minimum of another dataset.
Mesh (Dataset)	To make a mesh available for visualization and results analysis. Use a Mesh node in a plot group to get the actual plot.
Mirror 2D and Mirror 3D	To extend a solution defined on one side of an axis to the other side of the axis. Useful for visualization of a solution to an axisymmetric problem or plane of reflection.
Parameterized Curve 2D and Parameterized Curve 3D	To visualize data along a general parameterized curve in 2D or 3D. Use this dataset to create a line plot in its original dimension and as a line graph plot in 1D.

Response Spectrum 2D and Response Spectrum 3D	To perform a response spectrum analysis (a modal-based method for estimating the structural response to a transient, nondeterministic event). Requires the Structural Mechanics Module.
Revolution 1D and Revolution 2D	Use a revolution dataset to visualize a 2D or 1D axisymmetric solution in 3D and 2D, respectively.
Sector 2D and Sector 3D	To exploit symmetries in the model to reduce the model size and then, if needed, use rotations and reflections to plot the solution for the entire geometry.
Shell	To visualize the top and bottom surfaces of a shell in 3D. Requires the Structural Mechanics Module.
