The Style → Links menu provides style options, which allow you to choose the way all the links in the net are displayed. The menu is also available by right-clicking on the background and choosing Modify → Style Default Link.
Hidden: Toggling Style → Links → Hide Links allows you to hide all the links in the net. This is especially useful when you are creating something for an end-user who does not care how nodes are linked together (then you may also want to hide some nodes). To avoid confusion, it is not possible to display some links and hide others (although if the nodes at both ends of a link are hidden, the link between won't be drawn either).
Technical: The remaining 3 choices of the Style → Links menu are for those familiar with the process of Bayes net compiling, and wish to see how it is being done. They allow you to switch between showing the link structure of the net which was originally constructed (Style → Links → Regular Dag), the link structure of the Markov net derived from it (→ Markov Net), and the link structure of the triangulated net derived from the Markov network (→ Triangulated).
The triangulated net is used internally to determine the cliques when compiling the net, and a number is displayed with each node to indicate its position in the elimination order of the compilation.
The Triangulated
and Markov Net styles are
only for viewing the net, printing it, and copying its graphics (with
no nodes selected). If you try to do any other operation the style
will automatically change back to Regular Dag.
Before you choose these from the menu, you may want to save your
net, since they will loose information about link bends.
