.SH AVAILABILITY
.LP
These routines are available with the
.I Graphics
software installation option.
Refer to
.TX INSTALL
for information on how to install optional software.
.SH DESCRIPTION
.LP
These subroutines generate graphic output in a relatively
device-independent manner.  See
.BR plot (5)
for a description of their effect.
.B openpl(\|)
must be used before any of the others
to open the device for writing.
.B closepl(\|)
flushes the output.
.LP
String arguments to
.B label(\|)
and
.B linemod(\|)
are
null-terminated
and do not contain
.SM NEWLINE
characters.
.LP
Various flavors of these functions exist
for different output devices.
They are obtained by the following
.BR ld (1)
options:
.TP 15
.B \-lplot
device-independent graphics stream on standard output for
.BR plot (1G)
filters
