graph − draw a graph

SYNOPSIS

graph [ −a spacing [ start ]]  [ −b ]  [ −c string ] [ −g gridstyle ]  [ −l label ]

[ −m connectmode ] [ −s ]  [ −x [ l ] lower [ upper [ spacing ]]]

[ −y [ l ] lower [ upper [ spacing ]]] [ −h fraction ]  [ −w fraction ]  [ −r fraction ]

[ −u fraction ]  [ −t ] ...

DESCRIPTION

Graph 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.  Labels may be surrounded with quotes "...", in which case they may be empty or contain blanks and numbers; labels never contain newlines. 

A legend indicating grid range is produced with a grid unless the −s option is present. 

OPTIONS

Each option is recognized as a separate argument. 

−a spacing [ start ]
Supply abscissas automatically (they are missing from the input); spacing is the spacing (default 1).  start 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 string
String is the default label for each point. 

−g gridstyle
Gridstyle is the grid style: 0 no grid, 1 frame with ticks, 2 full grid (default). 

−l label is label for graph. 

−m connectmode
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 ] lower [ upper [ spacing ] ]
If l is present, x axis is logarithmic.  lowerandupper are lower (and upper) x limits.  spacing, if present, is grid spacing on x axis.  Normally these quantities are determined automatically. 

−y [ l ] lower [ upper [ spacing ] ]
If l is present, y axis is logarithmic.  lowerandupper are lower (and upper) y limits.  spacing, if present, is grid spacing on y axis.  Normally these quantities are determined automatically. 

−h fraction
is fraction of space for height.

−w fraction
is fraction of space for width.

−r fraction
is fraction of space to move right before plotting.

−u fraction
is fraction of space to move up before plotting.

−t Transpose horizontal and vertical axes.  (Option −x now applies to the vertical axis.) 

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.
