Connector Style
The connector style specifies how the links are connected at the nodes.
It is applied to those link ends that have the extremity
mode "Free". The options are:
- Fixed offset pins -
The connection pins are spaced along the node border at a distance equal
to the link offset parameter.
- Evenly spaced pins -
The connector pins are evenly spaced along the node border, preserving
a margin which is determined by the "evenly spaced pins margin ratio"
parameter (see the "Expert" tab).
- Automatic pins -
Determines automatically when to use fixed offset pins and when to use
evenly spaced pins.
- Mixed style -
The style of each individual node can have different connector style.
In order to specify the connector style of individual nodes,
set the global style to "Mixed style" first.
Then, select a node rule in the "Style Rules" while holding the Ctrl-key.
This node rule will appear selected additionally to the "GraphLayout" rule.
Then, choose the local connector style for these nodes.

Extremity Modes
The extremity mode specifies whether layout is allowed to freely move the
the connection point of a link at a node, or whether the connection point
is fixed. The extremity mode can be specified for the end point that connects
to the origin node and for the end point that connects to the destination
node. It can be specified globally for all links, or locally for individual
links.
In order to specify the extremity mode of individual links,
the corresponding global mode must be set to "Mixed" first.
Then, select a link rule in the "Style Rules" while holding the Ctrl-key.
This link rule will appear selected additionally to the "GraphLayout" rule.
Then, choose the local extremity mode for these links.
