Scope Tab
Determines which labels should be automatically positioned.
Place Node Labels
Whether or not to place node labels. Note that only node labels
that are not node internal will be placed. Use the node property dialog
to assign an external model like Eight Pos to the node labels.
Place Edge Labels
Whether or not to place edge labels.
Consider Selected Features Only
Whether or not to consider only labels of node or edges that
are selected.
Consider Invisible Labels
Whether or not to consider labels that are currently invisible.
Quality Tab
These options influence the overall quality of the layout.
Use Optimization
Whether or not to activate an optimized labeling algorithm.
If activated the resulting layout should contain fewer labels
that overlap. Activating optimization will slow down the layouter.
Optimization Strategy
The chosen optimization strategy affects the different kinds of overlaps of labels.
- None
- Use no optimization strategy. This will improve the runtime at the expense of quality.
- Balanced
- The impact of the different kinds of overlaps is balanced.
- Edge Overlap
- The algorithm tries to minimize the number of overlaps between labels and edges.
- Node Overlap
- The algorithm tries to minimize the number of overlaps between labels and nodes.
- Label Overlap
- The algorithm tries to minimize the number of overlaps between labels.
Allow Node Overlaps
Whether or not to allow that the labels overlap with nodes.
Note that even if this feature is deactivated there is still a
possibility that labels will overlap
with nodes if there is not enough space or the label model
is too restrictive.
Allow Edge Overlaps
Whether or not to allow labels to overlap with edges.
Note that even if this feature is deactivated there is still a
possibility that labels will overlap
with edges if there is not enough space or the label model
is too restrictive.
Use Postprocessing
Further optimization for the placement of edge labels with model Free.
Model Tab
Edge Label Model
Determines which positions will be available for the edge labels.
- Free
- There are no restrictions for the placement of labels.
- Best
- Currently equal to Free.
- As Is
-
Uses the individual label models that are currently set on the input graph.
Individual models for edge labels can be changed in the edge or edge label
property dialog. - Center Slider
- Allows labels to be placed somewhere on the corresponding edge path.
- Side Slider
- Allows labels to be placed along both sides of the edge path.
- Centered
- Allows labels to be placed on top of the center of the longest edge segment
- 3 Pos
-
Allows labels to be placed on top of the edge either at source or at target
or at center position of the edge path. - 2 Pos
-
Allows labels to be placed on top of the edge either at source or at target
position of the edge path.
