Layout Settings Dialog Window
This dialog window is used to control the settings and dimensions
of a graph visualization.
Modifying the dimensions has an influence on the extension of a
graph visualization, so if you do not want to reduce the scale of
a graph with dialog
then you can reduce the font size or the node distances here to
get a smaller visualization.
After changing the dimensions, the graph layout has to be
recalculated to deal with new node extensions, but the order of
nodes is preserved.
This way all interactive fine-tuning operations performed on a
graph layout will be lost afterwards.
So be sure to set the final dimensions before starting with
By selecting a smaller or larger font size, the other dimensions
in this window are adjusted proportionally.
The edge style, either straight lines or curves respective
splines, can also be controlled here.
This setting only affects long edges that span more than one
horizontal node level.
These long span edges are filled up with invisible dummy nodes at
each passed level.
Usually the segments of long span edges (starting at the parent,
going from dummy to dummy and ending at the child node) are drawn
with straight lines.
An optional spline edge style can be used which looks much more
The style of an edge can be individually controlled with edge
in the term representation of the graph.
If not defined, straight lines are used as default.
To overwrite the individual style settings, the global edge style
can be set in this dialog window.
when using splines, the dummy nodes are usually not laying on
the spline curve.
Instead, they are control points of the spline functions.
So especially when there are sharp bends in the spline, the edge
may overlap with neighbour nodes which is not the case when using

Font Size (pt)

and 34 point.
Changing the font size with this option button will also adjust

This is determined by the

To choose whether long span edges are drawn as straight
lines or as curves (splines).
When using "As defined in Graph", the actual style of each individual
edge is determined by the value of its
attribute in the term representation.
When not defined, straight lines are assumed as default.
These individual settings can be globally overwritten by using
either the "Straight Lines" or "Curves (Splines)" setting.
Specifies if the edge text should be always displayed in black or
in grey if the edge is unselected and only in black if the edge
is selected. Setting this option can lead to an unreadable
layout of the graph, because edge texts can cross nodes and other edges
or other edge texts.
