It is often useful to know how certain settings affect
the resulting layout of the graph after the layout algorithm has been
applied. The following table provides additional information about
the behavior of the layout algorithms.
Layout characteristics of layout algorithms
Layout algorithm |
Do the initial positions of the
nodes affect the layout? |
How do I get a different layout
of the same graph when I perform the layout a second time? |
---|---|---|
Yes |
In incremental mode, you can completely change
the layout by changing the initial positions of the nodes. To change
only the dimensions of the graph, use the preferred length of the
links or size of the layout region. See Preferred length (FL). |
|
Yes (if incremental mode is enabled) |
In incremental mode, you can change the layout
by changing the initial positions of the nodes. Furthermore, you can
change the layout by selecting a different Root node (TL). To change
only the dimensions of the graph, use the various offset parameters.
|
|
Yes (if incremental mode is enabled) |
In incremental mode, you can change the layout
by changing the initial positions of the nodes. Furthermore, you can
use specified node level indices to change the level structure. See Level index parameter (HL). You
can use specified node position indices to change the node order within
the levels. See Position index parameter (HL). You
can change the layout by changing the link priorities. See Link priority parameter (HL). To
change only the dimensions of the graph, use the various offset parameters. |
|
Short
Link Layout |
Yes |
Short Link Layout routes the links depending
on the node positions. It does not move the nodes. You can change
the link style option and the dimensional parameters, such as the
link offset and final segment length. You can also specify the rules
for computing the connection points of the links. |
Long
Link Layout |
Yes |
Long Link Layout routes the links depending
on the node positions. It does not move the nodes. You can change
the link style option and the dimensional parameters, such as the
link offset and final segment length. You can also specify the rules
for computing the connection points of the links. |
No |
It is the default behavior when using the
default parameter settings (the random generator is initialized differently
each time). |
|
No |
You can completely change the layout by using
clustering settings and the root clusters parameter. You can change
the dimensions of the graph by using the dimensional parameters. |
|
Yes (if incremental mode is enabled) |
You can change various dimensional parameters,
layout mode, and so on. |
