7 | .SH SYNOPSIS | |
8 | .B graph | |
9 | [ option ] ... | |
10 | .SH DESCRIPTION | |
11 | .I Graph | |
12 | with no options takes pairs of numbers from the | |
13 | standard input as abscissas and | |
14 | ordinates of a graph. | |
15 | Successive points are connected by straight lines. | |
16 | The graph is encoded on the standard output | |
17 | for display by the | |
604ebb9a | 18 | .IR plot (1G) |
43f216ce KM |
19 | filters. |
20 | .PP | |
21 | If the coordinates of a point are followed by | |
22 | a nonnumeric string, that string is printed as a | |
23 | label beginning on the point. | |
24 | Labels may be surrounded with quotes "...", in | |
25 | which case they may be empty or contain blanks | |
26 | and numbers; | |
27 | labels never contain newlines. | |
28 | .PP | |
29 | The following options are recognized, | |
30 | each as a separate argument. | |
31 | .TP | |
32 | .B \-a | |
33 | Supply abscissas automatically (they are missing from | |
34 | the input); spacing is given by the next | |
35 | argument (default 1). | |
36 | A second optional argument is the starting point for | |
37 | automatic abscissas (default 0 or lower limit given by | |
38 | .BR \-x ). | |
39 | .TP | |
40 | .B \-b | |
41 | Break (disconnect) the graph after each label in the input. | |
42 | .TP | |
43 | .B \-c | |
44 | Character string given by next argument | |
45 | is default label for each point. | |
46 | .TP | |
47 | .B \-g | |
48 | Next argument is grid style, | |
49 | 0 no grid, 1 frame with ticks, 2 full grid (default). | |
50 | .TP | |
51 | .B \-l | |
52 | Next argument is label for graph. | |
53 | .TP | |
54 | .B \-m | |
55 | Next argument is mode (style) | |
56 | of connecting lines: | |
57 | 0 disconnected, 1 connected (default). | |
58 | Some devices give distinguishable line styles | |
59 | for other small integers. | |
60 | .TP | |
61 | .B \-s | |
62 | Save screen, don't erase before plotting. | |
63 | .TP | |
64 | \fB\-x\fR [ \fBl\fR ] | |
65 | If | |
66 | .B l | |
67 | is present, x axis is logarithmic. | |
68 | Next 1 (or 2) arguments are lower (and upper) | |
69 | .IR x "" | |
70 | limits. | |
71 | Third argument, if present, is grid spacing on | |
72 | .I x | |
73 | axis. | |
74 | Normally these quantities are determined automatically. | |
75 | .TP | |
76 | \fB\-y\fR [ \fBl\fR ] | |
77 | Similarly for | |
78 | .IR y . | |
79 | .TP | |
80 | .B \-h | |
81 | Next argument is fraction of space for height. | |
82 | .TP | |
83 | .B \-w | |
84 | Similarly for width. | |
85 | .TP | |
86 | .B \-r | |
87 | Next argument is fraction of space to move right before plotting. | |
88 | .TP | |
89 | .B \-u | |
90 | Similarly to move up before plotting. | |
91 | .TP | |
92 | .B \-t | |
93 | Transpose horizontal and vertical axes. | |
94 | (Option | |
95 | .B \-x | |
96 | now applies to the vertical axis.) | |
97 | .PP | |
98 | A legend indicating grid range is produced | |
99 | with a grid unless the | |
100 | .B \-s | |
101 | option is present. | |
102 | .PP | |
103 | If a specified lower limit exceeds the upper limit, | |
104 | the axis | |
105 | is reversed. | |

110 | stores all points internally and drops those for which | |
111 | there isn't room. | |
112 | .br | |
113 | Segments that run out of bounds are dropped, not windowed. | |

115 | Logarithmic axes may not be reversed. |
