In the Designer, you can set the Graph Layout and Link
Layout options in the Style Rules pane, in order to lay out the nodes
and links in your graph according to a specific arrangement.
The graph layouts available are: bus, circular, grid,
hierarchical (the default), tree, uniform length edges.
The link layouts available are: hierarchical, short links,
long links.
Layout selection
There are many ways to select a layout, and you can choose
one according to which is most convenient for you:
The most commonly used layout is hierarchical. An example
project with the hierarchical layout is the genealogy example, <installdir>/jviews-diagrammer89/bin/designer/data/examples/genealogy.idpr.
Example projects with bus and circular layouts are also supplied in <installdir>/jviews-diagrammer89/bin/designer/data/examples.
Layout customization
If you need to customize the default behavior of a graph
or link
layout algorithm, or the parameters set by a layout theme,
you can select Graph Layout or Link Layout under Options and set properties
in the Styling Customizer.
The most common properties to use are those in the Control
and Basic tabs.
Where necessary, online Help text is available for individual
properties.
A few graph and link layout properties are set on a per-node
or per-link basis. Explanations and instructions for setting these
appear in the Styling Customizer. For an example, see
Setting a link style with mixed links.
