BusinessEvents Tools Layout Options Reference
Layout options refer to the style of the graph that is rendered in the Rule Analyzer and Rule Debugger Analyzer/Dependency panel.
Various options affect the appearance of a graph, no matter what layout is chosen. (The hierarchical layout offers additional options.) See the following sections for details:
The main layout options are:
Incremental Layout
Choose Incremental Layout if you want the main arrangement of the graph to remain stable when you make changes to your project and only re-route the entities and links that have changed since the last rendering.
Keeping most things in the same place makes it easier to see how changes you have made in the project affect the graph.
If you want to refresh the entire graph, click the desired layout option. The program has greater freedom to optimize the layout. The result is likely to be a more pleasing arrangement.
To perform an incremental layout update, do one of the following:
Hierarchical Layout
The hierarchical layout style indicates dependencies by positioning the nodes at different levels. The hierarchical layout style is useful when it is useful to show precedence relationships in the ontology. The hierarchical layout style indicates dependencies by positioning the nodes at different levels. You can use Layout Preferences to determine in the direction of the hierarchy. Preferences and options specific to the hierarchical layout are:
Orientation Options (Edit > Preferences)—Left to Right, Top to Bottom, Right to Left, Bottom to Top
Routing Options (View > Layout)—Orthogonal or normal (polyline) routing
Routing Options (Edit > Preferences)—Orthogonal or polyline routing.
See BusinessEvents Tools Preferences Reference for more details.
Orthogonal Layout
The orthogonal layout style uses only horizontal and vertical links. Graphs are drawn quickly.
The algorithm places highly connected nodes closer together, resulting in a more compact graph. Even when lines overlap, the algorithm ensures that they are still easy to follow. Because this style has no hierarchical or other visual constraints, the resulting graphs are often very clear.
Circular Layout
This layout is useful for ontologies where nodes tend to have a clustered (ring or star) structure (where each main node has a starburst of related nodes).
Symmetric Layout
The symmetric layout style looks for and emphasizes the symmetries in a project topology. It can produce a pleasing visual result, if there are no reasons to arrange the nodes for other reasons, for example there is no hierarchy or ring-clustering inherent in the structure of the nodes.
