.\" @(#)graph.1 6.1 (Berkeley) %G%
with no options takes pairs of numbers from the
standard input as abscissas and
Successive points are connected by straight lines.
The graph is encoded on the standard output
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
labels never contain newlines.
The following options are recognized,
each as a separate argument.
Supply abscissas automatically (they are missing from
the input); spacing is given by the next
A second optional argument is the starting point for
automatic abscissas (default 0 or lower limit given by
Break (disconnect) the graph after each label in the input.
Character string given by next argument
is default label for each point.
Next argument is grid style,
0 no grid, 1 frame with ticks, 2 full grid (default).
Next argument is label for graph.
Next argument is mode (style)
0 disconnected, 1 connected (default).
Some devices give distinguishable line styles
for other small integers.
Save screen, don't erase before plotting.
is present, x axis is logarithmic.
Next 1 (or 2) arguments are lower (and upper)
Third argument, if present, is grid spacing on
Normally these quantities are determined automatically.
Next argument is fraction of space for height.
Next argument is fraction of space to move right before plotting.
Similarly to move up before plotting.
Transpose horizontal and vertical axes.
now applies to the vertical axis.)
A legend indicating grid range is produced
If a specified lower limit exceeds the upper limit,
stores all points internally and drops those for which
Segments that run out of bounds are dropped, not windowed.
Logarithmic axes may not be reversed.
