The CANCEL PLOT Analyzer command resets the SET PLOT default
    qualifiers to their initial values. It also cancels the SET PLOT
    node specifications, if defined. The SET PLOT defaults are set
    with the SET PLOT command and specify qualifier defaults for
    PLOT and TABULATE commands which have node specifications. (PLOT
    and TABULATE commands without node specifications take their
    defaults from the currently active plot.) The SET PLOT defaults
    also specify all qualifier and nodespec defaults for PLOT and
    TABULATE commands that have the /DEFAULT qualifier.

    The CANCEL PLOT command resets the default qualifiers
    to the following values: /PC_SAMPLING, /NOMINIMUM,
    /NOMAXIMUM, /NOCUMULATIVE, /NOMAIN_IMAGE, /NOSCALE,
    /DESCENDING, /SOURCE, /NOSTACK_DEPTH, /ZEROS, /NOCHAIN_NAME,
    /NOPATH_NAME, /NOWRAP, /NOPARENT_TASK, /NOCREATOR_PC, and
    /FILL=("*","O","x","@",":","#","/","+").

    This command also resets the default node specification to
    PROGRAM_ADDRESS BY ROUTINE.
