The Selection subnode () provides the possibility to define a selection for some plots. Add it to make the plot appear only in some geometric entities (some domains, for example). Arrow Line, Arrow Point, Arrow Surface, Arrow Volume, Contour, Coordinate System Line, Coordinate System Surface, Coordinate System Volume, Isosurface, Line, Max/Min Line, Max/Min Surface, Max/Min Volume, Mesh, Multislice, Principal Stress Volume, Principal Stress Surface, and Principal Stress Line, Slice, Streamline, Surface, and Volume plots support the Selection attribute. In the Model Builder, add one of those plot types; then right-click the plot node and select Selection.

From the Selection list, choose Manual to select the geometric entities (domains or boundaries, for example, depending on the plot type) directly in the Graphics window or using the tools in the Selection section. You can also select All domains or All boundaries, for example, or any applicable selection defined in the model.
