GRAPH(1G)            INTERACTIVE UNIX System            GRAPH(1G)



          NAME
               graph - draw a graph

          SYNOPSIS
               graph [ options ]

          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 tplot(1G) filters.

               If the coordinates of a point are followed by a non-numeric
               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 new-lines.

               The following options are recognized, each as a separate
               argument:

               -a        Supply abscissas automatically (they are missing
                         from the input); spacing is given by the next
                         argument (default 1).  A second optional argument
                         is the starting point for automatic abscissas
                         (default 0 or lower limit given by -x).
               -b        Break (disconnect) the graph after each label in
                         the input.
               -c        Character string given by next argument is default
                         label for each point.
               -g        Next argument is grid style, 0 no grid, 1 frame
                         with ticks, 2 full grid (default).
               -l        Next argument is label for graph.
               -m        Next argument is mode (style) of connecting lines:
                         0 disconnected, 1 connected (default).  Some dev-
                         ices give distinguishable line styles for other
                         small integers (e.g., the Tektronix 4014: 2=dot-
                         ted, 3=dash-dot, 4=short-dash, 5=long-dash).
               -s        Save screen, do not erase before plotting.
               -x [ l ]  If l is present, x axis is logarithmic.  Next 1
                         (or 2) arguments are lower (and upper) x limits.
                         Third argument, if present, is grid spacing on x
                         axis.  Normally these quantities are determined
                         automatically.
               -y [ l ]  Similarly for y.
               -h        Next argument is fraction of space for height.
               -w        Similarly for width.
               -r        Next argument is fraction of space to move right
                         before plotting.
               -u        Similarly to move up before plotting.
               -t        Transpose horizontal and vertical axes.  (Option
                         -x now applies to the vertical axis.)

               A legend indicating grid range is produced with a grid
               unless the -s option is present.  If a specified lower limit
               exceeds the upper limit, the axis is reversed.

          BUGS
               The graph command 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.
