                      4: .sh SYNOPSIS

                      7: .sh DESCRIPTION
                      8: .it Plot
                      9: takes pairs of numbers from the
                     10: standard input as abscissas and
                     11: ordinates of a graph.
                     12: The graph is plotted on the storage scope, /dev/vt0.
                     13: .s3
                     14: The following options are recognized,
                     15: each as a separate argument.
                     16: .s3
                     17: .lp +5 5
                     18: \fBa\fR        Supply abscissas automatically (they are missing from
                     19: the input); spacing is given by the next
                     20: argument, or is assumed to be 1 if next argument is not a number.
                     21: .s3
                     22: .lp +5 5
                     23: \fBc\fR        Place character string given by next argument
                     24: at each point.
                     25: .s3
                     26: .lp +5 5
                     27: \fBd\fR        Omit connections between points. (Disconnect.)
                     28: .s3

                     33: \fIn\fR=0, no grid
                     34: .lp +5 0
                     35: \fIn\fR=1, axes only
                     36: .lp +5 0
                     37: \fIn\fR=2, complete grid (default).
                     38: .s3
                     39: .lp +5 5
                     40: \fBs\fR        Save screen, don't erase before plotting.
                     41: .s3
                     42: .lp +5 5
                     43: \fBx\fR        Next 1 (or 2) arguments are lower (and upper) \fIx\fR limits.
                     44: .s3
                     45: .lp +5 5
                     46: \fBy\fR        Next 1 (or 2) arguments are lower (and upper)
                     47: \fIy\fR limits.
                     48: .s3
                     49: .i0
                     50: Points are connected by straight line segments in the order
                     51: they appear in input.
                     52: If a specified lower limit exceeds the upper limit, or if
                     53: the automatic increment is negative, the graph is plotted
                     54: upside down.
                     55: Automatic abscissas begin with the lower \fIx\fR limit, or with 0
                     56: if no limit is specified.
                     57: Grid lines and automatically determined limits fall on round
                     58: values, however roundness
                     59: may be subverted by giving an inappropriately rounded
                     60: lower limit.
                     61: Plotting symbols specified by
                     62: .bd c
                     63: are
                     64: placed so that a small initial letter,
                     65: such as + o x, will fall
                     66: approximately on the plotting point.
