Use a Line plot to display a quantity on lines — that is, boundaries in 2D () or edges in 3D (). Add Deformation, Filter, or Height Expression (2D only) subnodes as needed. Right-click a 2D Plot Group or 3D Plot Group to add these plot types. It is possible to use 1D data in 2D and 3D line plots; the 1D data is then embedded into 2D or 3D, respectively.
