aiSee User Manual: Node-Group States
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.
The box operation can be chosen for a
- Subgraph (menu item Box Subgraph)
- Path region (Box Region…)
- Neighbor region (Box Neighbors…)
The reverse operation is Unfold/Unbox (or press the ‘u’ key).
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.
Clustering is an experimental feature. The layout of clustered subgraphs is quite challenging by nature. The experimental implementation of clustered layout is currently not supported nor maintained. Nevertheless, many aiSee users find this feature quite useful.
The cluster operation can only be chosen for subgraphs (menu item Cluster Subgraph) or summary nodes (Unfold into Cluster, or press the ‘t’ key). 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.
Wrapping
All nodes
and edges belonging to a group are wrapped using the same color. The layout is not changed.
The wrapping operation can only be chosen for subgraphs (menu item Wrap/Unwrap Subgraph).
The reverse operation is Wrap/Unwrap Subgraph. Nested wrapping is
not supported.
Displaying exclusively
A group of nodes is shown exclusively. Other nodes of the graph are not visible. Only edges between nodes of the group are visible. The exclusive displaying can be invoked for a
- Subgraph (menu item Exclusive Subgraph)
- Path region (Exclusive Region…)
- Neighbor region (Exclusive Neighbors…)
- Box (Exclusive)
- Summary node (Exclusive)
The reverse operation is All Subgraphs/Regions.
