• Neighbor region (menu item Fold Neighbors...), or • Box (menu item Fold Box). Summary nodes A summary node represents all the nodes of a group that was folded dynamically, i.e. by a folding operation, or statically, i.e. in the graph specification. A summary node can be selected and • Unfolded (menu item Unfold/Unbox or press the u key) • Unfolded into a box (menu item Unfold into Box or x) • Unfolded and represented as a cluster (menu item Unfold into Cluster or t) • Unfolded and wrapped (menu item Unfold and Wrap or w) • Drawn exclusively (menu item Exclusively) 4.2.2 Box A boxed group of nodes is surrounded by a frame, i. e. drawn in a nested box. The nodes inside the box are independent of the rest of the graph, i. e. there are no edges connecting nodes outside of the box with nodes inside the box or vice versa. The layout for the graph inside a box can differ from the layout of the outer graph. The layout calculation for graphs with boxes is fast since the nodes inside the box are independent of the rest of the graph and the layout of the box is calculated separately. Targets The box operation can be chosen for a • Subgraph (menu item Box Subgraph), • Path region (menu item Box Region...), or • Neighbor region (menu item Box Neighbors...). Reverse Operation The reverse operation is Unfold/Unbox (or press the u key). 4.2.3 Cluster A clustered group of nodes is surrounded by a frame. In contrast to a box, edges from nodes outside the frame are drawn to nodes inside the frame and vice versa. Here the layout is calculated as if the graph were unfolded, the only difference being that the nodes are placed according to the restrictions induced by the common frame. This often results in rather poor layout quality, layout calculation frequently being slow on account of the restrictions. Consequently, the boxed layout is preferable whenever possible. 30
Note: Clustering is an experimental feature. The layout of clustered subgraphs is quite challenging by nature. aiSee includes an experimental implementation of clustered layout which is currently not supported nor maintained. Nevertheless, many aiSee users find this feature quite useful. Targets The cluster operation can only be chosen for subgraphs (menu item Cluster Subgraph) or summary nodes (menu item Unfold into Cluster, or press the t key). Reverse Operation A direct reverse operation is not implemented. To reverse a cluster operation, change the clustered subgraph into a box or fold it and then use Unfold/Unbox. 4.2.4 Wrapping All nodes and edges belonging to a group are wrapped using the same color. The layout is not changed. Note: Nested wrapping is not supported. Targets The wrapping operation can only be chosen for subgraphs (Wrap/Unwrap Subgraph). Reverse Operation The reverse operation is Wrap/Unwrap Subgraph. 4.2.5 Displaying Exclusively A group of nodes is shown exclusively. Not all other nodes of the graph are visible. Only edges between nodes of the group are visible. Targets The exclusive displaying of groups of nodes can be chosen for a • Subgraph (menu item Exclusive Subgraph), • Path region (menu item Exclusive Region...), • Neighbor region (menu item Exclusive Neighbors...), • Box (menu item Exclusive), • Summary node (menu item Exclusive). Reverse Operation The reverse operation is All Subgraphs/Regions. 31
