GRAPH(VI) 2/20/75 GRAPH(VI) NAME graph - draw a graph SYNOPSIS graph [ option ] ... | plotter DESCRIPTION Graph with no options takes pairs of numbers from the standard input as abscissas and ordinates of a graph. The graph is written on the standard output to be piped to the plotter program for a particular device; see plot (VI). These plotters exist: gsip, for the GSI and other Diablo terminals; tek, for the Tektronix 4014 terminal; and vt0 for the on-line storage scope. 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, or is assumed to be 1 if next argument is not a number. A second optional argument is the starting point for the automatic abscissa. c Place character string given by next argument at each point. d Omit connections between points. (Disconnect.) gn Grid style: n=0, no grid n=1, axes only n=2, complete grid (default). s Save screen, don't erase before plotting. x Next 1 (or 2) arguments are lower (and upper) x limits. y Next 1 (or 2) arguments are lower (and upper) y limits. h Next argument is fraction of space for height w Next argument is fraction of space for width. r Next argument is fraction of space to move right before plotting. u Next argument is fraction of space to move up before plotting. Points are connected by straight line segments in the order they appear in input. If a specified lower limit exceeds the upper limit, or if the automatic increment is negative, the graph is plotted upside down. Automatic abscissas begin with the lower x limit, or with 0 if no limit is specified. Grid lines and automatically determined limits fall on round values, however roundness may be subverted by giving an inappropriately rounded lower limit. Plotting symbols specified by c are placed so that a small initial letter, such as + o x, will fall approximately on the plotting point.
