ORBIT EQUIVALENCE OF GRAPHS AND ISOMORPHISM OF GRAPH GROUPOIDS

We show that the groupoids of two directed graphs are isomorphic if and only if the two graphs are orbit equivalent by an orbit equivalence that preserves isolated eventually periodic points. We also ...

Example 4: Using ODS to Generate a Drill-down Graph

You can use ODS to generate a drill-down graph (see About Drill-down Graphs). All you have to do is supply the linking information that identifies the location of the target output. SAS/GRAPH produces ...

Example 3: Using a Web Driver to Generate a Drill-down Graph

This example shows how to use a SAS/GRAPH Web driver to generate a drill-down graph (see About Drill-down Graphs). The example uses the HTML driver, but the principles would be the same for using the ...
