graph with no options takes pairs of numbers from the standard input as abscissaes and ordinates of a graph. Successive 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.
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.
-m connectmode Mode (style) of connecting lines: 0 disconnected, 1 connected (default). Some devices give distinguishable 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.

|ATTRIBUTE TYPE||ATTRIBUTE VALUE|
lpr(1B), plot(1B), spline(1), plot(3PLOT), attributes(5)
graph stores all points internally and drops those for which there is no room.
Segments that run out of bounds are dropped, not windowed.
Logarithmic axes may not be reversed.
