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.

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? |
|---|---|---|
No |
You can completely change the layout by using the starting
node, outer cycle, and fixed nodes parameters. To change only
the dimensions of the graph, use the layout region parameter.
See Outer cycle (TML), Using fixed nodes (TML), and Layout region (TML).
|
|
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 (ULEL).
|
|
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. |
|
Yes |
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,
except in incremental mode |
You
change the dimensions of the graph by using the various
dimensional parameters. |
|
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. |

You can change the parameters of the sublayouts individually.

instance. You can change the parameters of the sublayouts
individually. |
