nodespec Specifies a program location. Node specifications (nodespecs) on PLOT and TABULATE commands define how the vertical axis of a histogram or table is partitioned into buckets. For example, the node specification PROGRAM_ADDRESS BY ROUTINE selects the program address domain, the domain of all possible program addresses. From this domain, it selects the address ranges of the routines in the program. Each of these address ranges defines a bucket. See HELP Nodespecs for information about node specifications.
