Hierarchic Bus Structures Demo
This demo shows how bus structures in the hierarchic layout can result in much more
compact arrangements.
So-called bus structures are related to edge grouping. A bus structure consists of a root
node and bus nodes that are directly connected to the root node. All edges connecting bus
nodes of the same structure have the same edge direction.
Demo Presets
The demo offers different configuration presets alongside an option to customize it
arbitrarily.
- Balanced
-
Each bus is assigned a default
HierarchicLayoutBusDescriptor
with no further configuration.
- Leaves
-
Each bus uses a
HierarchicLayoutBusDescriptor
where only one node is allowed before and after the bus by setting
maximumNodesAfterBus
and
maximumNodesBeforeBus
to one.
- Squares
-
The
HierarchicLayoutBusDescriptor
for each bus is configured separately such that its elements will be arranged in a
square.
- Left Aligned
-
Setting the
maximumNodesBeforeBus
to zero and allowing arbitrarily many nodes after the bus, results in a left alignment.
- Right Aligned
-
Setting the
maximumNodesAfterBus
to zero and allowing arbitrarily many nodes before the bus, results in a right
alignment.
- Custom
-
In this mode, you can play around with the sliders that control the
maximumNodesAfterBus
and
maximumNodesBeforeBus
setting to see its effect.
Things to Try
-
Click
Toggle Bus Structures
to see the difference between the layout without bus structures and the current bus
structure preset.
- Try the different bus structure presets in the dropdown menu.
-
Choose the
Custom
preset of the dropdown and try different settings for
maximumNodesAfterBus
and
maximumNodesBeforeBus
with the sliders.
-
Edit the graph and click the
button to re-run the layout with the current settings.
