NAME
plot: openpl et al. - graphics interface
SYNOPSIS
openpl( )
erase( )
label(s) char s[ ];
line(x1, y1, x2, y2)
circle(x, y, r)
arc(x, y, x0, y0, x1, y1)
move(x, y)
cont(x, y)
point(x, y)
linemod(s) char s[ ];
space(x0, y0, x1, y1)
closepl( )
DESCRIPTION
These subroutines generate graphic output in a relatively device-independent manner. See plot(5) for a description of their effect. Openpl must be used before any of the others to open the device for writing. Closepl flushes the output.
String arguments to label and linemod are null-terminated, and do not contain newlines.
Various flavors of these functions exist for different output devices. They are obtained by the following ld(1) options:
- -lplot
- device-independent graphics stream on standard output for plot(1)
filters
- -l300
- GSI 300 terminal
- -l300s
- GSI 300S terminal
- -l450
- DASI 450 terminal
- -l4014
- Tektronix 4014 terminal
