NAME
plot - graphics filter SYNOPSIS
plot [ file ... ] DESCRIPTION
Plot interprets plotting instructions (see plot(6)) from the files or standard input, drawing the results in a newly created 81/2(1) win- dow. Plot persists until a newline is typed in the window. Various options may be interspersed with the file arguments; they take effect at the given point in processing. Options are: -d Double buffer: accumulate the plot off-screen and write to the screen all at once when an erase command is encountered or at end of file. -e Erase the screen. -c col Set the foreground color (see plot(6) for color names). -f fill Set the background color. -g grade Set the quality factor for arcs. Higher grades give better quality. -p col Set the pen color. -w Pause until a newline is typed on standard input. -C Close the current plot. -W x0,y0,x1,y1 Specify the bounding rectangle of plot's window. By default it uses a 512x512 window in the middle of the screen. SOURCE

NAME
plot - graphics interface DESCRIPTION
Files of this format are produced by routines described in plot(3), and are interpreted for various devices by commands described in plot(1). A graphics file is a stream of plotting instructions. Each instruction consists of an ASCII letter usually followed by bytes of binary information. The instructions are executed in order. A point is designated by four bytes representing the x and y values; each value is a signed integer. The last designated point in an l, m, n, or p instruction becomes the `current point' for the next instruction. Each of the following descriptions begins with the name of the corresponding routine in plot(3). m move: The next four bytes give a new current point. n cont: Draw a line from the current point to the point given by the next four bytes. See plot(1). p point: Plot the point given by the next four bytes. l line: Draw a line from the point given by the next four bytes to the point given by the following four bytes. t label: Place the following ASCII string so that its first character falls on the current point. The string is terminated by a newline. a arc: The first four bytes give the center, the next four give the starting point, and the last four give 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 four bytes give the center of the circle, the next two the radius. e erase: Start another frame of output. f linemod: Take the following string, up to a newline, as the style for drawing further lines. The styles are `dotted,' `solid,' `long- dashed,' `shortdashed,' and `dotdashed.' Effective only in plot 4014 and plot ver. s space: The next four bytes give the lower left corner of the plotting area; the following four give the upper right corner. The plot will be magnified or reduced to fit the device as closely as possible. Space settings that exactly fill the plotting area with unity scaling appear below for devices supported by the filters of plot(1). The upper limit is just outside the plotting area. In every case the plotting area is taken to be square; points outside may be displayable on devices whose face isn't 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); SEE ALSO
