The NETDRAW Procedure |
In addition to the network precedence information, the Network data set may also contain other variables that can be used to change the default layout of the network. For example, the nodes of the network can be aligned in the horizontal direction using the ALIGN= specification, or they can be divided into horizontal bands (or zones) using a ZONE variable.
Table 5.15 lists all of the variables associated with the Network data set and their interpretations by the NETDRAW procedure. Note that all the variables are identified to the procedure in the ACTNET statement. Some of the variables use default names that are recognized by the procedure to denote specific information, as explained previously. The table indicates if the variable is default or needs to be identified in the ACTNET statement.
