.TH PLOT 5 .SH NAMEplot \- graphics interface.SH DESCRIPTIONFiles of this format are produced by routinesdescribed in .IR  plot (3),and are interpreted for various devicesby commands described in.IR  plot (1).A graphics file is a stream of plotting instructions.Each instruction consists of an ASCII letterusually followed by bytes of binary information.The instructions are executed in order.A point is designated byfour bytes representingthex and yvalues;each valueis a signed integer.The last designated point in an.B "l, m, n,"or.B pinstruction becomes the `current point'for the next instruction..PPEach of the following descriptions begins with the nameof the corresponding routine in.IR  plot (3)..TP 3.B  mmove: The next four bytes give a new current point..TP 3.B  ncont: Draw a line from the current point tothe point given by the next four bytes.See.IR  plot (1)..TP 3.B  ppoint: Plot the point given by the next four bytes..TP 3.B  lline: Draw a line from the point given by the nextfour bytes to the point given by the following four bytes..TP 3.B  tlabel: Place the following ASCII string so that itsfirst character falls on the current point.The string is terminated by a newline..TP 3.B  aarc:The first four bytes give the center, the next four give thestarting point,and the last four give the end point of a circular arc.The least significant coordinate of the end point isused only to determine the quadrant.The arc is drawn counter-clockwise..TP 3.B  ccircle:The first four bytes give the center of the circle,the next two the radius..TP 3.B  eerase: Start another frame of output..TP 3.B  flinemod: Take the following string, up to a newline,as the style for drawing further lines.The styles are`dotted,'`solid,' `longdashed,' `shortdashed,' and `dotdashed.'Effective only in .I plot 4014and.I plot ver..TP 3.B  sspace: The next four bytes givethe lower left corner of the plotting area;the following four give the upper right corner.The plot will be magnified or reduced to fitthe device as closely as possible..IPSpace settings that exactly fill the plotting areawith unity scaling appear below fordevices supported by the filters of.IR  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 ondevices whose face isn't square..RS.TP 10n4014space(0, 0, 3120, 3120);.br.ns.TP verspace(0, 0, 2048, 2048);.br.ns.TP 300, 300sspace(0, 0, 4096, 4096);.br.ns.TP 450space(0, 0, 4096, 4096);.RE.SH "SEE ALSO"plot(1), plot(3), graph(1)
