GRAPH(1) GRAPH(1) NAME graph - draw a graph SYNOPSIS graph [ option ... ] DESCRIPTION Graph with no options takes pairs of numbers from the stan- dard 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 dis- play 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 start- ing 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 distin- guishable 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.

Third argu- ment, 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.

Option -e actually makes automatic limits, rather than automatic scaling, equal.
