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.
