37: .SH DESCRIPTION
38: These subroutines generate graphic output in a relatively
39: device-independent manner. See
40: .IR plot (5)
41: for a description of their effect.
42: .I Openpl
43: must be used before any of the others to open the device for writing.
44: .I Closepl
45: flushes the output.
46: .PP
47: String arguments to
48: .I label
49: and
50: .I linemod
51: are null-terminated, and do not contain newlines.
52: .PP
53: Various flavors of these functions exist for different output devices.
54: They are obtained by the following
55: .IR ld (1)
56: options:
57: .TP 8n
58: .B \-lplot

129: .PP
130: On many devices, it is necessary to pause after
131: .IR erase (),
132: otherwise plotting commands are lost.
133: The pause is normally done by the tty driver if at login time,
134: .I tset
135: found a
136: .I df
137: field in the
138: .IR termcap (5)
139: entry for the terminal.
140: If a pause is needed but not automatically being generated,
