for a graph and if animation is turned on, meaning a rate or animation speed is given, the user can<br />
follow the movement of the nodes from their initial positions in the layout to the newly calculated<br />
ones. The rate or speed refers to the number of animated iterations. (cf. graph attribute amax,<br />
p. 66).<br />
The value of Neighbor Region Range describes the extent of the neighbor region (see p. 28).<br />
4.4 Changing the Layout<br />
The submenu Layout of the Misc menu in the menu lineoffers the following possibilities to<br />
change the layout of the graph:<br />
• Layout...<br />
Changes the layout for an individual graph, i. e. either for an individual subgraph or the<br />
top-level graph only. This operation can also be invoked by pressing the l key.<br />
• Pass Layout...<br />
Changes the layout parameters for the selected graph (subgraph or top-level graph) and then<br />
passes the setting of all the layout parameters of the selected graph to all its subgraphs.<br />
• Pass Changes...<br />
Changes the layout parameters for the selected graph (subgraph or top-level graph) and then<br />
passes only the setting of the changed layout parameters of the selected graph to all its<br />
subgraphs.<br />
After selecting one of these items a boxed subgraph can be chosen for which the layout is to be<br />
changed by left-clicking in the box. Right-clicking causes the layout of the top-level graph to be<br />
changed.<br />
After that the Layout dialog box appears, where the layout parameters can be changed. The layout<br />
parameters take effect when the dialog box is closed by selecting the OK button. This yields a new<br />
layout of the graph. Clicking on Cancel causes the old parameters to remain in effect.<br />
The following layout parameters can be changed:<br />
• Layout Attributes<br />
This section it can be specified whether edge labels are to be drawn, what they look like,<br />
where they are positioned and what the edges are to look like.<br />
– Edge labels (see display_edge_labels on p. 69)<br />
– Dirty labels (see dirty_edge_labels on p. 69)<br />
– Near edges (see near_edges attribute on p. 80)<br />
– Double edges<br />
If this option is disabled doubled edges are not drawn, i. e. if more than one edge exists<br />
between a source node and a target node, only one edge is drawn between these nodes<br />
(see also summarize option on p. 126)<br />
