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 terminated 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, shortdashed, 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.
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
