5 Manipulating Graphs
5.3 Expanding and collapsing graphs You may often find that you are only interested in certain nodes of a graph. Other nodes may be of no interest and it is useful, especially in large graphs, to be able to remove their children from the display. You can do this in a number of ways.
To collapse or expand any node in a graph, double-click on it. Thus, double-click on a leaf node to display its children (if it has any), and double-click on a non-leaf node to hide its children.
Figure 5.2 Expanding and collapsing nodes
For instance, in Figure 5.2, double-click on A to display B, C and D. Double-click on A once again to hide them.
You can also collapse or expand several nodes at once as follows:
- Choose Graph Layout > Expand Nodes to expand all the selected nodes in the graph.
- Choose Graph Layout > Collapse Nodes to collapse all the selected nodes in a graph.
