 NAME     
 SYNOPSIS     
 DESCRIPTION     
 |  |  |  | Graph with no options takes pairs of numbers from the standard
    input as abscissas (x-values) and ordinates (y-values) of a graph.
    Successive 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.
 −p    Next argument is one or more of the characters bcgkmrwy, choosing
    pen colors by their initial letter, as in plot(6). Successive
    curves will cycle through the colors in the given order.
 −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 limits,
    rather than automatic scaling, equal.
