GRAPH(1G)                            BSD                             GRAPH(1G)



NAME
     graph - draw a graph

SYNOPSIS
     graph [ option ] ...

DESCRIPTION
     The graph command with no options takes pairs of numbers from the
     standard input as abscissas and ordinates of a graph.  Successive points
     are connected by straight lines. The graph is encoded on the standard
     output for display by the plot(1G) filters.

     If the coordinates of a point are followed by a nonnumeric string, that
     string is printed as a label beginning on the point.  You can enclose
     labels in quotation marks "..."; if you do, the labels can be empty or
     contain blanks and numbers; labels never contain newlines.

OPTIONS
     graph recognizes the following options, each as a separate argument.

     -a        Supply abscissas automatically (they are missing from the
               input); spacing is given by the next argument (the default is
               1).  A second optional argument is the starting point for
               automatic abscissas (the default is 0 or a lower limit given by
               the -x option).

     -b        Break (disconnect) the graph after each label in the input.

     -c string The character string given by string is the default label for
               each point.

     -g style  Use the grid style, style:  0 for no grid, 1 for frame with
               ticks, 2 for full grid (2 is the default).

     -l label  Use the string label as the label for the graph.

     -m mode   Use mode as the mode (style) of connecting lines:  0 for
               disconnected, 1 for connected (1 is the default).  Some devices
               give distinguishable line styles for other small integers.

     -s        Save screen, don't erase before plotting.

     -x [[[ l ] u ] s ]
               If l is present, the x axis is logarithmic.  The next one (or
               two) arguments are the lower (and upper) x limits.  The third
               argument, if present, is the grid spacing on the x axis.
               Normally these quantities are determined automatically.

     -y  [[[ l ] u ] s ]
               If l is present, the y axis is logarithmic.  The next one (or
               two) arguments are the lower (and upper) y limits.  The third
               argument, if present, is the grid spacing on the y axis.
               Normally these quantities are determined automatically.

     -h n      Use n as the fraction of space for height.

     -w n      Use n as the fraction of space for width.

     -r n      Use n as the fraction of space to move to the right, before
               plotting.

     -u n      Use n as the fraction of space to move up before plotting.

     -t        Transpose the horizontal and vertical axes.  (that is, option
               -x now applies to the vertical axis.)

     graph produces a legend indicating the grid range with a grid, unless the
     -s option is present.

     If a specified lower limit exceeds the upper limit, the axis is reversed.

BUGS
     graph stores all points internally and drops those for which there isn't
     room.
     Segments that run out of bounds are dropped, not windowed.
     Logarithmic axes may not be reversed.
