PLOT(3) Library Functions Manual PLOT(3) NAME pl_openpl, pl_erase, pl_label, pl_line, pl_circle, pl_arc, pl_move, pl_cont, pl_point, pl_linemod, pl_space, pl_closepl, pl_dot, pl_box, pl_openvt, pl_closevt - plotting interface SYNOPSIS #include <plot.h> #include <plotcompat.h> /* compatibility with old libplot */ void pl_openpl(void); void pl_erase(void); void pl_label(char *s); void pl_line(int x1, int y1, int x2, int y2); void pl_circle(int x, int y, int r); void pl_arc(int x, int y, int x0, int y0, int x1, int y1); void pl_move(int x, int y); void pl_cont(int x, int y); void pl_point(int x, int y); void pl_linemod(char *s); void pl_space(int x0, int y0, int x1, int y1); void pl_closepl(void); void pl_dot(int xi, int yi, int dx, int n, int *pat); void pl_box(int x0, int y0, int x1, int y1); void pl_openvt(void); void pl_closevt(void); DESCRIPTION These subroutines generate graphic output in a relatively device-indepen- dent manner. See plot(5) for a description of their effect. pl_openpl() or pl_openvt() must be used before any of the others to open the device for writing. pl_closepl() and pl_closevt() flushes the output, but pl_clo- sevt() is often used when error occurs. String arguments to pl_label() and pl_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 -lplot4013 Tektronix 4013 terminal -lplot4014 Tektronix 4014 and 4015 terminals with the Enhanced Graphics Module (Use -l4013 for 4014's or 4015's without the Enhanced Graphics Mod- ule) -lplotbg BBN bitgraph graphics terminal -lplotdumb Dumb terminals without cursor addressing or line printers -lplotgigi DEC vt125 terminals -lplot7221 Hewlett Packard 7221 graphics terminal -lplotcrt Any crt terminal capable of running vi. -lplotimagen Imagen laser printer (default 240 dots-per-inch resolution). On many devices, it is necessary to pause after pl_erase(), otherwise plot- ting commands are lost. The pause is normally done by the tty driver if at login time, tset found a df field in the termcap(5) entry for the terminal. If a pause is needed but not automatically being generated, add flush(stdout); sleep(1); after each pl_erase(). SEE ALSO plot(5), plot(1), f77plot(3), graph(1) 7th Edition July 31, 2018 PLOT(3)
