NAME

       graph - draw a graph

SYNOPSIS

       graph [ option ] ...

DESCRIPTION

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

       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 newlines.

       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 devices  give  distinguishable  line
	      styles for other small integers.

       -s     Save screen, don't 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

       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.

NAME

       graph - draw a graph

SYNOPSIS

       graph [ option ...  ]

DESCRIPTION

       Graph  with no options takes pairs of numbers from the standard input as abscissas (x-values) and ordinates (y-values) of a graph.  Succes-
       sive points are connected by straight lines.  The graph is encoded on the standard output for display by plot(1) filters.

       If an ordinate is 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 newlines.

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

       -a     Supply  abscissas  automatically;  no  x-values  appear  in 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 1 with a log scale in x, or the 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  a  legend  to title the graph.  Grid ranges are automatically printed as part of the title unless a -s option is
	      present.

       -m     Next argument is mode (style) of connecting lines: 0 disconnected, 1 connected.  Some devices give distinguishable line  styles  for
	      other small integers.  Mode -1 (default) begins with style 1 and rotates styles for successive curves under option -o.

       -o     (Overlay.)  The ordinates for n superposed curves appear in the input with each abscissa value.  The next argument is n.

       -s     Save screen; no new page for this graph.

       -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.

       -e     Make automatically determined x and y scales equal.

       -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 -a now applies to the vertical axis.)

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

BUGS

       Segments that run out of bounds are dropped, not windowed.  Logarithmic axes may not be reversed.  Option -e actually makes automatic  lim-
       its, rather than automatic scaling, equal.
