plot(S-osr5)


plot -- graphics interface subroutines

Syntax

cc . . . -lplot

int arc(x, y, x0, y0, x1, y1)
int x, y, x0, y0, x1, y1;

int box(x0, y0, x1, y1) int x0, y0, x1, y1;

int circle(x, y, r) int x, y, r;

int closepl()

int cont(x, y) int x, y;

int erase()

int label(s) char *s;

int line(x1, y1, x2, y2) int x1, y1, x2, y2;

int linemod(s) char *s;

int move(x, y) int x, y;

int openpl()

int point(x, y) int x, y;

int space(x0, y0, x1, y1) int x0, y0, x1, y1;

Description

These subroutines generate graphic output in a relatively device-independent manner. space must be used before any of these functions to declare the amount of space necessary (see plot(FP)). openpl must be used before any of the others to open the device for writing. closepl flushes the output.

box draws a box using the four coordinates specified as arguments.

circle draws a circle of radius r with center at the point (x, y).

arc draws an arc of a circle with center at the point (x, y) between the points (x0, y0) and (x1, y1).

String arguments to label and linemod are terminated by nulls and do not contain new-lines.

See plot(FP) for a description of the effect of the remaining functions.

The library files listed below provide several flavors of these routines.

Return value

Even though all routines have integer retun values, no meaningful value is returned.

Files

/usr/lib/libplot.a produces output for tplot(ADM) filters
/usr/lib/lib300.a for DASI 300
/usr/lib/lib300s.a for DASI 300s
/usr/lib/lib450.a for DASI 450
/usr/lib/lib4014.a for TEKTRONIX 4014

 /usr/lib/libplot.a   produces output for tplot(ADM) filters
 /usr/lib/lib300.a    for DASI 300
 /usr/lib/lib300s.a   for DASI 300s
 /usr/lib/lib450.a    for DASI 450
 /usr/lib/lib4014.a   for TEKTRONIX 4014

Warnings

To compile a program containing these functions in file.c, it is necessary to use:
   cc file.c -lplot
In order to execute it, it is necessary to use:
   a.out | tplot
Since the plot routines use the stdio.h header file, programs that do not use standard I/O are increased in size more than might be expected.

Standards conformance

The plot package is not part of any currently supported standard; it is an extension of AT&T System V provided by the Santa Cruz Operation.
