When I saw this I had my first cup of coffee and the thought passed across
my mind "hold on, are things like plot(4B) still around?" and now I almost
feel motivated to go look. I am surprised that graph(1) and spline(1) were
still around at all.
For the sake of the maillist .. here are the man pages from those very
very old guys ( from Solaris 8 ):

User Commands graph(1)
NAME
graph - draw a graph
SYNOPSIS
graph [ -a spacing [ start ] ] [ -b ] [ -c string ] [
-g gridstyle ] [ -l label ] [ -m connectmode ] [ -s ] [
-x [ l ] lower [ upper [ spacing ] ] ] [ -y [ l ]
lower [ upper [ spacing ] ] ] [ -h fraction ] [
-w fraction ] [ -r fraction ] [ -u fraction ] [ -t ]
...
DESCRIPTION
graph with no options takes pairs of numbers from the stan-
dard input as abscissaes and ordinates of a graph. Succes-
sive points are connected by straight lines. The standard
output from graph contains plotting instructions suitable
for input to plot(1B) or to the command lpr -g (see
lpr(1B)).
If the coordinates of a point are followed by a nonnumeric
string, that string is printed as a label beginning on the
point. Labels may be surrounded with quotes "...", in which
case they may be empty or contain blanks and numbers; labels
never contain NEWLINE characters.
A legend indicating grid range is produced with a grid
unless the -s option is present.
OPTIONS
Each option is recognized as a separate argument. If a
specified lower limit exceeds the upper limit, the axis is
reversed.
-a spacing[ start ]
Supply abscissaes automatically (they are missing from
the input); spacing is the spacing (default 1). start
is the starting point for automatic abscissaes
(default 0 or lower limit given by -x).
-b Break (disconnect) the graph after each label in the
input.
-c string
String is the default label for each point.
-g gridstyle
Gridstyle is the grid style: 0 no grid, 1 frame with
ticks, 2 full grid (default).
-l label
label is label for graph.

User Commands graph(1)
-m connectmode
Mode (style) of connecting lines: 0 disconnected, 1
connected (default). Some devices give distinguish-
able line styles for other small integers.
-s Save screen, do not erase before plotting.
-x [ l ] lower [ upper [ spacing ] ]
If l is present, x axis is logarithmic. lower and
upper are lower (and upper) x limits. spacing, if
present, is grid spacing on x axis. Normally these
quantities are determined automatically.
-y [ l ] lower [ upper [ spacing ] ]
If l is present, y axis is logarithmic. lower and
upper are lower (and upper) y limits. spacing, if
present, is grid spacing on y axis. Normally these
quantities are determined automatically.
-h fraction
fraction of space for height.
-w fraction
fraction of space for width.
-r fraction
fraction of space to move right before plotting.
-u fraction
fraction of space to move up before plotting.
-t Transpose horizontal and vertical axes. Option -x now
applies to the vertical axis.

User Commands spline(1)
NAME
spline - interpolate smooth curve
SYNOPSIS
spline [ -aknpx ] ...
DESCRIPTION
spline takes pairs of numbers from the standard input as
abcissas and ordinates of a function. It produces a similar
set, which is approximately equally spaced and includes the
input set, on the standard output. The cubic spline output
(R. W. Hamming, Numerical Methods for Scientists and
Engineers,2nd ed., 349ff) has two continuous derivatives,
and sufficiently many points to look smooth when plotted,
for example by graph(1).
OPTIONS
-a Supply abscissas automatically (they are missing from
the input); spacing is given by the next argument, or
is assumed to be 1 if next argument is not a number.
-k The constant k used in the boundary value computation
(2nd deriv. at end) = k*(2nd deriv. next to end)
is set by the next argument. By default k = 0.
-n Space output points so that approximately n intervals
occur between the lower and upper x limits. (Default
n = 100.)
-p Make output periodic, that is, match derivatives at
ends. First and last input values should normally
agree.
-x Next 1 (or 2) arguments are lower (and upper) x lim-
its. Normally these limits are calculated from the
data. Automatic abcissas start at lower limit (default
0).

DIAGNOSTICS
When data is not strictly monotonic in x, spline reproduces
the input without interpolating extra points.
BUGS
A limit of 1000 input points is enforced silently.

Now I *almost* feel motivated to go looking for the oldest old-geek binary
hiding in there. I recall using plot(1B) once upon a time but again that
is from the UCB world.
Anyways ... good morning.
