Inside the Graph Box

A Graph box in the main workspace looks like this:


When you double left click on the graph box a dialog box opens:



If you choose "Directed Acyclic Graph," you will only be able to construct directed acyclic graphs. That is, you will only be allowed to constructed directed (-->) edges, and you will not be permitted to construct cycles in your graph (X-->...-->X for some variable X in your graph). See Directed Acyclic Graphs.

If you choose "(General) Graph," you will be permitted to construct edges between variables with endpoints of the following three types: segment (-), arrow (->), and circle (-o). See General Graphs.

If you choose "Time Series Graph," you will be permitted to construct directed graphs over time-lagged variables for a give set of variables X1,..., Xn. See Time Series Graphs.

 

Choosing a graph type

Here is some general advise for picking graph types.
