GRAPH(1G)                DOMAIN/IX SYS5                 GRAPH(1G)



NAME
     graph - draw a graph

USAGE
     graph [options]

DESCRIPTION
     Graph with no options takes pairs of numbers from the stan-
     dard input as abscissas and ordinates of a graph.  Succes-
     sive 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.

NOTES
     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.
