NAME
+ +
+ + plot – graphics interface
+ +
+

DESCRIPTION
+ +
+ + Files of this format are interpreted by plot(1) to draw graphics + on the screen. A plot file is a UTF stream of instruction lines. + Arguments are delimited by spaces, tabs, or commas. Numbers may + be floating point. Punctuation marks (except :) , spaces, and + tabs at the beginning of lines are ignored. Comments run from + : to newline. Extra letters appended to a valid instruction are + ignored. Thus ...line, line, li all mean the same thing. Arguments + are interpreted as follows:
+ 1.    If an instruction requires no arguments, the rest of the line + is ignored.
+ 2.    If it requires a string argument, then all the line after the + first field separator is passed as argument. Quote marks may be + used to preserve leading blanks. Strings may include newlines + represented as \n.
+ 3.    Between numeric arguments alphabetic characters and punctuation + marks are ignored. Thus line from 5 6 to 7 8 draws a line from + (5, 6) to (7, 8).
+ 4.    Instructions with numeric arguments remain in effect until a + new instruction is read. Such commands may spill over many lines. + Thus the following sequence will draw a polygon with vertices + (4.5, 6.77), (5.8, 5.6), (7.8, 4.55), and (10.0, 3.6).
+ +
+ + move 4.5 6.77 + vec 5.8, 5.6 7.8 + 4.55 10.0, 3.6 4.5, 6.77 + + + + +
+ The instructions are executed in order. The last designated point + in a line, move, rmove, vec, rvec, arc, or point command becomes + the ‘current point’ (X,Y) for the next command.
+
Open & Close
+ o string   Open plotting device. For troff, string specifies the + size of the plot (default is 6i).
+ cl      Close plotting device.
+
Basic Plotting Commands
+ e       Start another frame of output.
+ m x y    (move) Current point becomes x y.
+ rm dx dyCurrent point becomes X+dx Y+dy.
+ poi x yPlot the point x y and make it the current point.
+ v x y    Draw a vector from the current point to x y.
+ rv dx dyDraw vector from current point to X+dx Y+dy
+ li x1 y1 x2 y2
+ +
+ + +
+ + Draw a line from x1 y1 to x2 y2. Make the current point x2 y2.
+ +
+ +
+ t string   Place the string so that its first character is centered + on the current point (default). If string begins with \C (\R), + it is centered (right-adjusted) on the current point. A backslash + at the beginning of the string may be escaped with another backslash.
+ a x1 y1 x2 y2 xc yc r
+ +
+ + +
+ + Draw a circular arc from x1 y1 to x2 y2 with center xc yc and + radius r. If the radius is positive, the arc is drawn counterclockwise; + negative, clockwise. The starting point is exact but the ending + point is approximate.
+ +
+ +
+ ci xc yc r
+ +
+ + +
+ + Draw a circle centered at xc yc with radius r. If the range and + frame parameters do not specify a square, the ‘circle’ will be + elliptical.
+ +
+ +
+ di xc yc r
+ +
+ + +
+ + Draw a disc centered at xc yc with radius r using the filling + color (see cfill below).
+ +
+ +
+ bo x1 y1 x2 y2
+ +
+ + +
+ + Draw a box with lower left corner at x1 y1 and upper right corner + at x2 y2.
+ +
+ +
+ sb x1 y1 x2 y2
+ +
+ + +
+ + Draw a solid box with lower left corner at x1 y1 and upper right + corner at x2 y2 using the filling color (see cfill below).
+ +
+ +
+ par x1 y1 x2 y2 xg yg
+ +
+ + +
+ + Draw a parabola from x1 y1 to x2 y2 ‘guided’ by xg yg. The parabola + passes through the midpoint of the line joining xg yg with the + midpoint of the line joining x1 y1 and x2 y2 and is tangent to + the lines from xg yg to the endpoints.
+ +
+ +
+ pol { {x1 y1 ... xn yn} ... {X1 Y1 ... Xm Ym} } + +
+ + +
+ + Draw polygons with vertices x1 y1 ... xn yn and X1 Y1 ... Xm Ym. + If only one polygon is specified, the inner brackets are not needed.
+ +
+ +
+ fi { {x1 y1 ... xn yn} ... {X1 Y1 ... Xm Ym} } + +
+ + +
+ + Fill a polygon. The arguments are the same as those for pol except + that the first vertex is automatically repeated to close each + polygon. The polygons do not have to be connected. Enclosed polygons + appear as holes.
+ +
+ +
+ sp { {x1 y1 ... xn yn} ... {X1 Y1 ... Xm Ym} } + +
+ + +
+ + Draw a parabolic spline guided by x1 y1 ... xn yn with simple + endpoints.
+ +
+ +
+ fsp { {x1 y1 ... xn yn} ... {X1 Y1 ... Xm Ym} } + +
+ + +
+ + Draw a parabolic spline guided by x1 y1 ... xn yn with double + first endpoint.
+ +
+ +
+ lsp { {x1 y1 ... xn yn} ... {X1 Y1 ... Xm Ym} } + +
+ + +
+ + Draw a parabolic spline guided by x1 y1 ... xn yn with double + last endpoint.
+ +
+ +
+ dsp { {x1 y1 ... xn yn} ... {X1 Y1 ... Xm Ym} } + +
+ + +
+ + Draw a parabolic spline guided by x1 y1 ... xn yn with double + endpoints.
+ +
+ +
+ csp { {x1 y1 ... xn yn} ... {X1 Y1 ... Xm Ym} } + in filename
+ +
+ + +
+ + (include) Take commands from filename.
+ +
+ +
+ de string { commands } + +
+ + +
+ + Define string as commands.
+ +
+ +
+ ca string scale
+ +
+ + +
+ + Invoke commands defined as string applying scale to all coordinates.
+ +
+ +
+
Commands Controlling the Environment
+ co string
+ +
+ + +
+ + Use color given by first character of string, one of red, yellow, + green, blue, cyan, magenta, white, and kblack. If string begins + with a digit, it is taken to be a 32-bit number specifying 8 bit + each of red, green, blue, and alpha. For example, 0xFFFF00FF denotes + solid yellow. + +
+ +
+ pe string
+ +
+ + +
+ + Use string as the style for drawing lines. The available pen styles + are: solid, dott[ed], short, long, dotd[ashed], cdash, ddash + +
+ +
+ cf string
+ +
+ + +
+ + Color for filling (see co, above).
+ +
+ +
+ ra x1 y1 x2 y2
+ +
+ + +
+ + The data will fall between x1 y1 and x2 y2. The plot will be magnified + or reduced to fit the device as closely as possible.
+ Range 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 with nonsquare faces. + +
+ +
+ fr px1 py1 px2 py2
+ +
+ + +
+ + Plot the data in the fraction of the display specified by px1 + py1 for lower left corner and px2 py2 for upper right corner. + Thus frame .5 0 1. .5 plots in the lower right quadrant of the + display; frame 0. 1. 1. 0. uses the whole display but inverts + the y coordinates.
+ +
+ +
+ sa      Save the current environment, and move to a new one. The new + environment inherits the old one. There are 7 levels.
+ re      Restore previous environment.
