plot(5) File Formats Manual plot(5) Name plot - graphics interface Description Files in this format are produced by the routines described in and are interpreted for various devices by commands described in A graphics file is a stream of plotting instructions. Each instruction consists of an ASCII letter, usually followed by bytes of binary information, executed in order. A point is designated by 4 bytes representing the x and y values and each value is a signed integer. The last designated point in an or instruction becomes the current point for the next instruction. In the following descriptions, the name of the corresponding routine in is enclosed in parenthesis: a (arc) The first 4 bytes are the center, the next 4 provide the starting point, and the last 4 bytes designate the end point of a circular arc. The least significant coordinate of the end point is used only to determine the quadrant. The arc is drawn counter-clockwise. c (circle) The first 4 bytes provide the center of the circle and the next 2 bytes designate the radius. e (erase) Start another frame of output. f (linemod) Take the following string, up to a new line, as the style for drawing further lines. The styles are dotted, solid, long- dashed, shortdashed, and dotdashed. This is only effective in the following plots: 4014, ver, lvp16, and hp7475a. l (line) Draw a line from the point designated by the next 4 bytes to the point provided by the following 4 bytes. m (move) The next 4 bytes provide a new current point. n (cont) Draw a line from the current point to the point designated by the next 4 bytes. For further information, see p (point) Plot the point provided by the next 4 bytes. s (space) The next 4 bytes give the lower left corner of the plotting area. The following 4 bytes give the upper right corner. The plot is magnified or reduced to fit the device as closely as possible. Space settings that fill the plotting area with unity scaling are listed below for devices supported by the filters of In each of the following cases, the plotting area is assumed square; points outside the square can be displayed on devices that have areas which are not square: 4014 space(0, 0, 3120, 3120); ver space(0, 0, 2048, 2048); 300, 300s space(0, 0, 4096, 4096); 450 space(0, 0, 4096, 4096); aed space(0, 0, 511, 482) bitgraph space(0, 0, 768, 1024) dumb space(0, 0, 132, 90) gigi space(0, 0, 767, 479) grn space(0, 0, 512, 512) hp7221 space(0, 0, 1800, 1800) lvp16 space(0, 0, 10365, 7962) (Paper Size: MET A) space(0, 0, 16640, 10365) (Paper Size: MET B) space(0, 0, 11040, 7721) (Paper Size: US A4) space(0, 0, 16150, 11040) (Paper Size: US A3) space(0, 0, 7721, 7721) (Default) hp7475a Same as for lvp16. t (label) Place the first character of the following ASCII string on the current point. This string is terminated by a newline char- acter. See Also graph(1g), plot(1g), plot(3x) plot(5)

plot, arc, box, circle, closepl, closevt, cont, erase, label, line, linemod, move, openpl, openvt, point, space - graphics interface SYNOPSIS
cc [ flag ... ] file ... -lplot [ library... ] #include <plot.h> void arc(short x0, short y0, short x1, short y1, short x2, short y2); void box(short x0, short y0, short x1, short y1); void circle(short x, short y, short r); void closepl(); void closevt(); void cont(short x, short y); void erase(); void label(char *s); void line(short x0, short y0, short x1, short y1); void linemod(char *s); void move(short x, short y); void openpl(); void openvt(); void point(short x, short y); void space(short x0, short y0, short x1, short y1); DESCRIPTION
These functions generate graphics output for a set of output devices. The format of the output is dependent upon which link editor option is used when the program is compiled and linked (see Link Editor). The term "current point" refers to the current setting for the x and y coordinates. The arc() function specifies a circular arc. The coordinates (x0, y0) specify the center of the arc. The coordinates (x1, y1) specify the starting point of the arc. The coordinates (x2, y2) specify the end point of the circular arc. The box() function specifies a rectangle with coordinates (x0, y0), (x0, y1), (x1, y0), and (x1, y1). The current point is set to (x1, y1). The circle() function specifies a circle with a center at the coordinates (x, y) and a radius of r. The closevt() and closepl() functions flush the output. The cont() function specifies a line beginning at the current point and ending at the coordinates (x, y). The current point is set to (x, y). The erase() function starts another frame of output. The label() function places the null terminated string s so that the first character falls on the current point. The string is then ter- minated by a NEWLINE character. The line() function draws a line starting at the coordinates (x0, y0) and ending at the coordinates (x1, y1). The current point is set to (x1, y1). The linemod() function specifies the style for drawing future lines. s may contain one of the following: dotted, solid, longdashed, short- dashed, or dotdashed. The move() function sets the current point to the coordinates (x, y). The openpl() or openvt() function must be called to open the device before any other plot functions are called. The point() function plots the point given by the coordinates (x, y). The current point is set to (x, y). The space() function specifies the size of the plotting area. The plot will be reduced or enlarged as necessary to fit the area specified. The coordinates (x0, y0) specify the lower left hand corner of the plotting area. The coordinates (x1, y1) specify the upper right hand corner of the plotting area. Link Editor Various flavors of these functions exist for different output devices. They are obtained by using the following ld(1) options: -lplot device-independent graphics stream on standard output in the format described in plot(4B) -l300 GSI 300 terminal -l300s GSI 300S terminal -l4014 Tektronix 4014 terminal -l450 GSI 450 terminal -lvt0 FILES
