1 | .TH GRAPH 1G |
| 2 | .SH NAME | |
| 3 | graph \- draw a graph | |
| 4 | .SH SYNOPSIS | |
| 5 | .B graph | |
| 6 | [ option ] ... | |
| 7 | .SH DESCRIPTION | |
| 8 | .I Graph | |
| 9 | with no options takes pairs of numbers from the | |
| 10 | standard input as abscissas and | |
| 11 | ordinates of a graph. | |
| 12 | Successive points are connected by straight lines. | |
| 13 | The graph is encoded on the standard output | |
| 14 | for display by the | |
| 15 | .IR plot (1) | |
| 16 | filters. | |
| 17 | .PP | |
| 18 | If the coordinates of a point are followed by | |
| 19 | a nonnumeric string, that string is printed as a | |
| 20 | label beginning on the point. | |
| 21 | Labels may be surrounded with quotes "...", in | |
| 22 | which case they may be empty or contain blanks | |
| 23 | and numbers; | |
| 24 | labels never contain newlines. | |
| 25 | .PP | |
| 26 | The following options are recognized, | |
| 27 | each as a separate argument. | |
| 28 | .TP | |
| 29 | .B \-a | |
| 30 | Supply abscissas automatically (they are missing from | |
| 31 | the input); spacing is given by the next | |
| 32 | argument (default 1). | |
| 33 | A second optional argument is the starting point for | |
| 34 | automatic abscissas (default 0 or lower limit given by | |
| 35 | .BR \-x ). | |
| 36 | .TP | |
| 37 | .B \-b | |
| 38 | Break (disconnect) the graph after each label in the input. | |
| 39 | .TP | |
| 40 | .B \-c | |
| 41 | Character string given by next argument | |
| 42 | is default label for each point. | |
| 43 | .TP | |
| 44 | .B \-g | |
| 45 | Next argument is grid style, | |
| 46 | 0 no grid, 1 frame with ticks, 2 full grid (default). | |
| 47 | .TP | |
| 48 | .B \-l | |
| 49 | Next argument is label for graph. | |
| 50 | .TP | |
| 51 | .B \-m | |
| 52 | Next argument is mode (style) | |
| 53 | of connecting lines: | |
| 54 | 0 disconnected, 1 connected (default). | |
| 55 | Some devices give distinguishable line styles | |
| 56 | for other small integers. | |
| 57 | .TP | |
| 58 | .B \-s | |
| 59 | Save screen, don't erase before plotting. | |
| 60 | .TP | |
| 61 | \fB\-x\fR [ \fBl\fR ] | |
| 62 | If | |
| 63 | .B l | |
| 64 | is present, x axis is logarithmic. | |
| 65 | Next 1 (or 2) arguments are lower (and upper) | |
| 66 | .IR x "" | |
| 67 | limits. | |
| 68 | Third argument, if present, is grid spacing on | |
| 69 | .I x | |
| 70 | axis. | |
| 71 | Normally these quantities are determined automatically. | |
| 72 | .TP | |
| 73 | \fB\-y\fR [ \fBl\fR ] | |
| 74 | Similarly for | |
| 75 | .IR y . | |
| 76 | .TP | |
| 77 | .B \-h | |
| 78 | Next argument is fraction of space for height. | |
| 79 | .TP | |
| 80 | .B \-w | |
| 81 | Similarly for width. | |
| 82 | .TP | |
| 83 | .B \-r | |
| 84 | Next argument is fraction of space to move right before plotting. | |
| 85 | .TP | |
| 86 | .B \-u | |
| 87 | Similarly to move up before plotting. | |
| 88 | .TP | |
| 89 | .B \-t | |
| 90 | Transpose horizontal and vertical axes. | |
| 91 | (Option | |
| 92 | .B \-x | |
| 93 | now applies to the vertical axis.) | |
| 94 | .PP | |
| 95 | A legend indicating grid range is produced | |
| 96 | with a grid unless the | |
| 97 | .B \-s | |
| 98 | option is present. | |
| 99 | .PP | |
| 100 | If a specified lower limit exceeds the upper limit, | |
| 101 | the axis | |
| 102 | is reversed. | |

| 106 | .I Graph | |
| 107 | stores all points internally and drops those for which | |
| 108 | there isn't room. | |
| 109 | .br | |
| 110 | Segments that run out of bounds are dropped, not windowed. | |
| 111 | .br | |
| 112 | Logarithmic axes may not be reversed. |
