The NETDRAW Procedure |
This example illustrates using the TREE option to draw organizational charts. The Network data set, DOCUMENT, describes how the procedures are distributed between two volumes of the SAS/OR documentation. The structure can be visualized easily in a tree diagram. The data set DOCUMENT contains the parent-child relationship for each node of the diagram. For each node, a detailed description is contained in the variable ID. In addition, the variable _pattern specifies the pattern to be used for each node. PROC NETDRAW is invoked with the TREE option, which illustrates the organization of the documentation in the form of a tree diagram drawn from left to right. The CENTERID option centers text within each node. Arrowheads are not necessary for this diagram and are suppressed by specifying ARROWHEAD=0. Output 9.15.1 shows the resulting diagram.
