- The GNU Graphics Utilities
- **************************
-
- The GNU graphics utilities are a set of programs for plotting
- scientific data. The program `graph' reads data files and writes a
- stream of plotting commands in a device independent format refered
- to below as a GNU plot file. The remaining programs provide support
- for displaying GNU plot files on tektronix 4010, PostScript (TM)*,
- and X window system compatible output devices.
-
- `graph' reads both ascii and binary data files and writes a plot
- file with or without axes and labels. You can specify labels and
- ranges for the axes, and you can set the sizes and position of the
- plot on the page. Each invocation of graph produces a plot with
- single set of axes and data. You can place an arbitrary number of
- plots on the page by concatenating the plot output of several
- invocations.
-
- `plot2ps' is a utility for converting plot files into PostScript.
- The `plot2ps' utility reads plotting commands from named files or
- the standard input and writes PostScript to the standard output.
- You can then print the PostScript output on a printer, or edit it
- using the `idraw' graphics editor. You can also easily include the
- output in LaTeX documents using `dvips' and the LaTeX command `psfig'.
-
- Why is this useful? The plot file format is a common standard on
- un*x systems. To produces figures for publication, you might need
- to take data sets, and produce labeled figures from them. This can
- be done using `graph', `plot2ps' and the `idraw' editor. You can
- also include these figures in LaTeX documents using the `dvips'
- utility. All of these utilities, as well as the plot file format
- and plot library, are discussed in the following sections.
-
- This documentation is under revision. Any comments, suggestions,
- or additions would greatly benifit GNU users. Please mail them to
- either `bug-gnu-utils@prep.ai.mit.edu' or `Rich@Rice.edu'.

-
- Simple examples using graph
- ===========================
-
- By default, `graph' reads ascii data from the standard input or
- files specified on the command line. `graph' reads pairs of values,
- x and y coordinates:
-
- 0.0 0.0
- 1.0 0.2
- 2.0 0.0
- 3.0 0.4
- 4.0 0.2
- 5.0 0.6
-
- To plot this data, you might use
-
- graph < ascii_data_file |plot
-
- where ascii_data_file could contain data similar to the above
- example. You can replace the command `plot' with `plot2tek' if you
- have
- a tektronix 4010 compatible graphics terminal, `plot2ps' if you have
- a postscript compatible printer or previewer, or `xplot' if you have
- an X window system display.
-
- Note that `graph' is commonly supplied with some operating systems.
- If so, some confusion may arise if the system supplied version is
- executed mistakenly. On unix systems, you can determine which
- version you invoke by typing the command `which graph', which prints
- the file name of the version you invoke by default.
-
- To reduce the change the size of the plot and position it in the
- middle of the display, you could use
-
- graph -h .4 -w .4 -r .2 -u .2 < ascii_data_file |plot
-
- where `h' and `w' are the height and width of the plot and `r' and
- `u' indicate how far up and to the right the plot is positioned.
-
- You can put symbols at each data point using
-
- graph -S 2 .01 < ascii_data_file |plot
-
- where 2 indicates which symbol to plot, and .01 indicates it's size.
-
- You can choose the type of line draw on each curve:
-
- graph -m 2 < ascii_data_file |plot
-
- where 2 indicates what kind of line connects the data points.
-
- File: graphics.info, Node: Input Files, Next: Overlaying, Prev: Invocation, Up: graph examples
-
- The format of input to `graph'
- ==============================
-
- As mentioned above, by default `graph' reads ascii pairs of
- values, x and y coordinates, from the standard input or files
- specified on the command line. Optional labels may be placed after
- each coordinate in the data file. The label ends at the end of the
- line:
-
- 3.0 0.4 this is a label for point (3.0, 0.4).
-
- The label must be enclosed in double quotes if it would otherwise
- be appear to be a coordinate:
-
- 3.0 0.4 "5.0 looks like a value."
-
- You can use the `-b' to break lines after each label in the input.
- Use a pair of empty double quotes if you need to break a line, but
- do not need a label.
-
- 0.0 0.0
- 2.0 0.0
- 1.0 0.2
- ""
- 0.0 0.1
- 2.0 0.2
- 4.0 0.3
-
- You can also break cuves using `-M' option to break lines whenever
- the abscissal values between successive pairs of points decrease.
- When using `-M', each continuous curve has monotonicly increasing
- abscissal values.
-
- 0.0 0.0 first data set
- 2.0 0.0
- 4.0 0.2
- 0.0 0.1 second data set
- 2.0 0.2
- 4.0 0.3
-
- `graph' will automaticly generate abscissal values for you if you
- specify the `-a' option. Only ordinate values are given in the
- data, and the data is then assumed to be equally sampled along the
- abscissa. The values following `-a' on the command line specify the
- sampling interval and the abscissal value of the first data point.
-
- 0.0
- 0.1
- 0.2 label for point (2.0, 0.2)
- 0.3
- 0.2
- 0.3
-
- File: graphics.info, Node: Overlaying, Next: Multiple Plots, Prev: Input Files, Up: graph examples
-
- Combining several data sets in one plot
- =======================================
-
- There are cases where you will want to superimpose several data
- sets or several plots on top of each other. If for example, the
- data sets are in seperate files, you can specify each by it's name
- on the command line. Since `graph' reads the standard input only if
- no files are named on the command line, you must add the name `--'
- if you want `graph' to read the standard input as well.
-
- graph data-file-one data-file-two data-file-three |plot
-
- For comparison sake, you might wish to distinguish the data in one
- set from another either by using different symbols at each point or
- by distinguishing the type of line draw. You can do this by
- preceeding each file name with options affecting the synbol or line
- style used to plot that data.
-
- graph -S 1 data-file-one -S 3 data-file-two -S 4 data-file-three |plot
-
- or
-
- graph -m 1 data-file-one -m 3 data-file-two -S 4 data-file-three |plot
-
- If you need to superimpose several data sets, but must invoke
- graph seperately for each, you will have to specify the limits of
- the axes.
-
- graph -x 0 100 -y -3 3 -S 3 -m -1 < ascii_data_file_1 >> plot_file
-
- where `-x 0 100' specifies the limits on the x axis, `-y -3 3'
- specifies
- the limits on the y axis, `-S 2' specifies a box to be drawn at each
- point, and `-m -1' specifies that no line is to be draw connecting
- the points. You can overlay a second data set on the first by using:
-
- graph -s -g 0 -x 0 100 -y -3 3 -m 0 < ascii_data_file_1 >> plot_file
-
- where `-s' avoids erasing the page, `-g 0' avoids drawing the
- axis, tick marks and labels which were drawn previously, and `-m 0'
- specifies that solid lines are draw connecting the points.
-
- File: graphics.info, Node: Multiple Plots, Next: Binary Data, Prev: Overlaying, Up: graph examples
-
- How to put multiple plots on one page
- =====================================
-
- The command
-
- graph -h .4 -w .4 -r .1 -u .1 < ascii_data_file_1 > plot_file
-
- will put a single box containing the plot in the lower left hand
- quarter
- of the page. You can add another plot to the upper left hand corner
- of the page using the command
-
- graph -s -h .4 -w .4 -r .1 -u .6 < ascii_data_file_2 >> plot_file
-
- Be sure you use the `-s' option so the the first plot isn't erased.
-
- Likewise you can add plots to the right hand side of the page using
-
- graph -s -h .4 -w .4 -r .6 -u .1 < ascii_data_file_3 >> plot_file
- graph -s -h .4 -w .4 -r .6 -u .6 < ascii_data_file_4 >> plot_file
-
- The tick marks can be moved inside the box and labels moved to the
- opposite sides using
-
- graph -T -.005 < ascii_data_file >> plot_file
-
- File: graphics.info, Node: Binary Data, Prev: Multiple Plots, Up: graph examples
-
- Reading other data formats
- ==========================
-
- `graph' will read binary data in integer, short integer, float,
- and double float format when you use the `-d' option followed by
- `f', or `d', respectively. There are two advantage to using binary
- data: 1) `graph' runs significantly faster because the computational
- overhead for converting data from ascii to binary is eliminated, and
- 2) the input files can be significantly smaller than the ascii
- format would be. Double float is the fastest format to read, while
- short integer is the most space conservative. If you have very
- large data sets, using a binary format can reduce storage and
- runtime costs.
-
- For example, you can create double float data as output from C
- language programs:
-
- #include <stdio.h>
- void write_point (x, y)
- double x, y;
- {
- fwrite(&x, sizeof (double), 1, stdout);
- fwrite(&y, sizeof (double), 1, stdout);
- }
-
- You can then plot data written this way using:
-
- graph -d d <datafile >plotfile
-

-
- Graph Command Line Options
- ==========================
-
- The following table describes each of the command line arguments
- to graph. Each option which takes an argument is followed by the
- type and default values of the argument in parentheses.
-
- `-a [STEP_SIZE [LOWER_LIMIT]]'
- `+auto-abscissa [STEP_SIZE [LOWER_LIMIT]]'
- (floats, defaults 1 and 0) Automaticly generate abscissa (x)
- values. This option specifies that the data contains only
- ordinate (y) values. The difference between successive x
- values will be STEP_SIZE, and the first x value will be
-
- LOWER_LIMIT. To return to reading abscissal values from the
- input you can specify `-a 0', which disables automatic
-
- generation of the abscissa and returns STEP_SIZE and
- LOWER_LIMIT to their default values.
-
- `-b'
- `+break-on-labels'
- Assumes multiple data sets are in the data file, and the data
- sets are separated by a label. The default is don't break on
- labels.
-
- `-M'
- `+break-non-monotone'
- When successive abscissa (x) values decrease, a separate data
- set is assumed. This allows multiple data sets in each file.
- Similar to `-b'.
-
- `-f SIZE'
- `+fontsize SIZE'
- Specify the size of the desired font as SIZE points. Not all
- display devices will honor this command.
-
- `-N X|Y'
- `+no-label X|Y'
- By default, values at each tick mark are labeled beside the
- axis. This option removes the labeling of the tick marks on the
- specified axis.
-
- `-R'
- `+dont-round-to-next-tick'
- By default, the ends of the axes are extended to the next tick
- mark. This option prohibits rounding the limits of the axes to
- the next tick mark.
-
- `-c STRING'
- `+point-label STRING'
- This option defines STRING as the default label for each point.
- Any label in the input will override this default.
-
- `-S SYMBOL_NUMBER [SYMBOL_SIZE]'
- `+symbol SYMBOL_NUMBER [SYMBOL_SIZE]'
- (integer and float, defaults -1 and 0.01) Draw a symbol at each
- point in the data. SYMBOL_NUMBER specifies the shape of the
- symbol according to the following table and SYMBOL_SIZE
- specifies the fractional size of the symbol with respect to the
- height and width of the plot. Note that you can specify
- symbols to be drawn without any line connecting them by
- specifying the option `-m -1'.
-
- -1 no symbol at all
- 0 plus sign (+)
- 1 cross (x)
- 2 star (*)
- 3 box
- 4 diamond
- 5 circle
- `-T TICK_SIZE'
- `+ticksize TICK_SIZE'
- (float, default .01) TICK_SIZE is the fractional size of the
- tick marks on each axis. A value of 1.0 produces tick marks on
- the x (y) axis whose length is equal to the width (height) of
- the plot.
-
- `-X X_LABEL'
- `+xtitle X_LABEL'
- (string, default blank) X_LABEL is a label printed below the x
- axis.
-
- `-Y Y_LABEL'
- `+ytitle Y_LABEL'
- (string, default blank) Y_LABEL is a label printed to the right
- of the y axis.
-
- `-d DATA-FORMAT'
- `+data-format DATA-FORMAT'
- This specifies what format the input data is in. Note labels
- can be used only in ascii format input files.
-
- `a'
- `A'
- ascii data
-
- `i'
- `I'
- binary integer data
-
- `s'
- `S'
- binary short integer data
-
- `f'
- `F'
- binary float data
-
- `d'
- `D'
- binary double data
-
- `+debug'
- Debugging information, including the data read in, is sent to
- the standard error output.
-
- `-g GRID_STYLE'
- `+grid GRID_STYLE'
- (integer, default 1) GRID_STYLE specifies the type of box
- framing the plot and whether grid lines are drawn inside the box.
-
- 0 no box around plot, no axes, no labels.
- 1 box containing a grid and axes with tick marks and labels.
- 2 box around plot, tick marks around the box and labels.
- 3 box around plot, ticks on left and lower sides only and labels.
- 4 axes intersect at the origin without a box or grid.
- `-h HEIGHT'
- `+height-plot HEIGHT'
- (float, default 0.8) HEIGHT specifies the fractional height of
- the plot with respect to the height of the plotting area. A
- value of 1.0 will produce a box which fills the available area.
- Note that the tick marks and labels are outside this area so
- that values less than 1.0 are generally used.
-
- `-L TOP_LABEL'
- `+toptitle TOP_LABEL'
- (string, default blank) TOP_LABEL is a label placed above the
- plot.
-
- `-m LINE_MODE'
- `+linestyle LINE_MODE'
- (integer, default 0) LINE_MODE specifies the mode (or style) of
- lines drawn between data points.
-
- -1 no line at all
- 0 solid
- 1 dotted
- 2 shortdashed
- 3 dotdashed
- 4 longdashed
- 5 disconnected
- `-r RIGHT'
- `+right-margin-posn RIGHT'
- (float, default 0.1) Move the plot to the right by a fractional
- amount RIGHT with respect to the width of the plotting area.
- This produces a margin on the left hand side of the plot. A
- value of 0.5 will produce a margin half the width of the
- available area. Note that the tick marks and labels are drawn
- in the margin.
-
- `-u UP'
- `+bottom-margin-posn UP'
- (float, default 0.1) Move the plot up by a fractional amount UP
- with respect to the height of the plotting area. This produces
- a margin below the plot. A value of 0.5 will produce a margin
- half the height of the available area. Note that the tick
- marks and labels are drawn in the margin.
-
- `-s'
- `+save-screen'
- Save the screen. This option prevent graph from erasing the
- previous contents of the graphics window or device.
-
- `-t'
- `+transpose'
- Transpose the abscissa and ordinate. This option causes the
- axes to be interchanged, and the options which apply to each
- axis to be applied to the opposite axis. That is, data is read
- in as (y, x) pairs and `-x', `-X' and `-lx' apply to the y axis.
-
- `-w WIDTH'
- `+width-plot WIDTH'
- (float, default 0.8) WIDTH specifies the fractional width of the
- plot with respect to the width of the plotting area. A value
- of 1.0 will produce a box which fills the available area. Note
- that the tick marks and labels are outside this area, so values
- less than 1.0 are generally used.
-
- `-x LOWER_LIMIT UPPER_LIMIT'
- `+xlimits LOWER_LIMIT UPPER_LIMIT'
- (floats) The arguments LOWER_LIMIT and UPPER_LIMIT specify the
- limits of the x axis. By default the upper and lower limits are
- taken from the data. If unspecified the limits of the data are
- used.
-
- `-y LOWER_LIMIT UPPER_LIMIT'
- `+ylimits LOWER_LIMIT UPPER_LIMIT'
- These arguments specify the scale and limits of the y axis as
- for the x axis above.
-
- `-l X|Y'
- `+log-axis X|Y'
- The argument indicates which axis should be a log axis. Either
- one or both x- and y-axes can be specified by using the
- appropriate letter. Use XY or YX to specify both.
-
- `+high-byte-first'
- `+low-byte-first'
- These options force graph to use the specified byte order when
- writing out the plot file. By default the byte order is host
- dependent.

-
- Examples Using `plot2ps'
- ========================
-
- To produce a plot of data arranged in ordered pairs of x and y
- coordinates in an ASCII file, you can use:
-
- graph <asciiDataFile | plot2ps | lpr -Plw
-
- To create a simple PostScript figure you can use:
-
- echo 0 0 1 1 2 0 | spline | graph | plot2ps > test.ps
-
- To edit the plot:
-
- idraw test.ps
-
- To use the previewer to look at the plot:
-
- gs test.ps
-
- File: graphics.info, Node: plot2ps invocation, Next: xplot, Prev: plot2ps examples, Up: Top
-
- Plot2ps Command Line Options
- ============================
-
- `plot2ps' is a relatively simple utility in that there are few
- command line options to choose from. The plot file format does not
- contain methods for specifying font or font size, so you must
- specify these things with options. There are no other options for
- controlling the picture.
-
- The plot file format is machine dependent on the byte order of
- unformatted, signed, two byte integer coordinates contained in plot
- commands. The `-high-byte-first' or `-low-byte-first' option
- specifies this order explicitly. `plot2ps' attempts to determine
- the byte order from commands early in the plot file, but the method
- is heuristic and is not foolproof. Several standard plot sizes
- specified by the `open' command are used to recognize byte order by
- `plot2ps'. If these sizes are recognized in byte reversed order,
- `plot2ps'
- adjusts accordingly. These sizes include 504x504, 2048x2048
- (versatek plotters), 2100x2100, 3120x3120(tektronix 4010 terminals)
- and 4096x4096 (gsi 300 terminals).
-
- The remaining command line options may be used specify an
- alternate PostScript prologue and to print the licensing information.
-
- Input plot files names may be specified anywhere on the command
- line. If no file names are specified, or the name `-' is specified,
- the standard input is read for plotting instructions. Only the font
- or font size options which precede a file name will affect the text
- for that file.
-
- `-H'
- `+help'
- The help option prints a summary of command line syntax for
- `plot2ps', a list of the font names (the standard builtin
- PostScript fonts), and version, copyright and warranty
- information. Specifying this options causes plot2ps to ignore
- files on the standard input. You can specify a file on the
- standard input explicitly with the option `-' if you want it to
- read the standard input as well.
-
- `-v'
- `-V'
- `+version'
- This option prints version, copyright and warranty information.
-
- `-fontsize SIZE'
- `-f SIZE'
- The fontsize options specifies the default size in printer's
- points (1/72 inch) of all text appearing in the plot. If
- unspecified, the size defaults to 14 points.
-
- Some sizes are supported better than others under X windows.
- The standard sizes distributed with X windows are 8, 10, 12,
- 14, 18, and 24 points. Text at these point sizes will display
- correctly in the `idraw' editor. Other font sizes will print
- correctly on a PostScript device such as the laserwriter, but
- may not appear at the correct size in the `idraw' editor.
-
- `-font NAME'
- `-fo NAME'
- The font name option specifies the name of the default font for
- all text appearing in the plot. `plot2ps -help' prints a
- listing of the font names on the standard output. These names
- include the available builtin fonts on standard PostScript
- printers.
-
- `-high-byte-first'
- `-h'
- The high-byte-first option specifies explicitly that the higher
- order byte of each signed, two byte integer occurs first in the
- file. It disables determination of byte order from the file
- itself.
-
- `-line-width WIDTH'
- WIDTH is the width of lines drawn in the plot, and defaults to a
- value of 0. A value of 0 will produce the thinest line
- possible in a device dependent fashion, however this is known
- to cause problems for older versions of idraw. The line width
- is device independent for a positive values of WIDTH.
-
- `-low-byte-first'
- `-l'
- The low-byte-first option specifies explicitly that the lower
- order byte of each signed, two byte integer occurs first in the
- file. It disables determination of byte order from the file
- itself.
-
- `-prologue FILENAME'
- `-p FILENAME'
- The prologue option specifies the name of an alternate
- PostScript prologue FILENAME to be used in place of the default
-
- `idraw' prologue. The prologue declares procedures used to
- draw each graphic object. The default prologue was generously
- provided by John Interante and is a part of the InterViews
- distribution, version 2.5.
-
- `-copying'
- `-warranty'
- The copying and warranty options print a copy of the GNU General
- Public License on the standard error output. Included is
- conditions for copying `plot2ps' and information on the lack of
- any warranty.
-
- These conditions do not cover the output of `plot2ps'. The only
- conditions imposed on the output are those which come from the
- prologue that you are using.
-
- `-signed'
- `-unsigned'
- The signed and unsigned options specify whether coordinates in
- the plot file are signed. By convention, coordinates are
- always signed. Some plot files do not follow this convention,
- and you can use the unsigned option to convert those files.
-
- `-bbox'
- The bbox option specifies that a bounding box comment will be
- written at the end of the output file. This information is
- useful for document preparation systems which determine how to
- size and place the figure using the bounding box. See also the
- atend script.

-
- A plot file previewer for X11
- =============================
-
- `xplot' is a plot file previewer for the X window system. It
- reads GNU plot commands from its standard input and draws the
- resulting graphics in an X window.
-
- After xplot reaches the end-of-file on the input, it puts itself
- in the background (forks). Control returns to the calling program,
- while xplot continues, remaining on screen.
-
- To exit, click the left mouse button in the xplot window. Note
- that xplot ignores SIGHUP signals, so you must use another signal to
- kill xplot if necessary.
-

-
- Xplot Options
- =============
-
- `xplot' accepts all of the standard X toolkit command line
- options, and the initial geometry specification determines the
- resolution, with a default geometry of 500x500 pixels.
-
- The following standard X Toolkit command line arguments may be
- used with `xplot':
-
- `-bg COLOR'
- This specifies the color to use for the background of the
- window. The default is WHITE.
-
- `-bd COLOR'
- This specifies the color to use for the border of the window.
- The default is BLACK.
-
- `-bw NUMBER'
- This specifies the width in pixels of the border surrounding the
- window.
-
- `-fg COLOR'
- This specifies the color to use for displaying text. The
- default is BLACK.
-
- `-fn FONT'
- This specifies the font to be used for displaying normal text.
- The default is 6X10.
-
- `-rv'
- This indicates that reverse video should be simulated by
- swapping the foreground and background colors.
-
- `-geometry GEOMETRY'
- This specifies the preferred size and position of the plot window.
-
- `-display HOST:DISPLAY'
- This specifies the X server to contact.
-
- `-xrm RESOURCESTRING'
- This specifies a toolkit resource property. See the manual page
- for xrdb.
-
- `xplot' uses the athena Command widget in the X Toolkit. So, it

-
- `reverseVideo'
- (class ReverseVideo) Specifies that the foreground and
- background colors should be reversed.
-
- Example
- -------
-
- The resources:
-
- Xplot.font: 6x9
- Xplot.geometry: 300x300
-
- will set the font used in the plot window to `6x9' and the size of
- the window to 300 by 300 pixels.

- Using Plot2fig
- ==============
-
- To create a simple plot file one can use:
-
- echo 0 0 1 1 2 0 | spline | graph | plot2fig > test.fig
-
- To edit the plot:
-
- fig test.fig
-
- To convert the fig file into dvi code, create a latex file
- containing a document which includes the figure:
-
- \\documentstyle\[\]{article}
- \\begin{document}
- \\input{test}
- \\end{document}
-
- Then, run transfig on the figure and latex on the document:
-
- % transfig -L latex test.fig
- % make test.tex
- % latex t.tex
-
- To edit a plot of data arranged in ordered pairs of x and y
- coordinates in an ascii file, one can use:
-
- % graph <asciiDataFile | plot2fig >file.fig
- % fig file.fig

-
- A plot file to fig file translator
- ==================================
-
- `plot2fig' reads plotting instructions from the specified input
- files and/or the standard input and produces `Fig' compatible code
- on it's standard output. This output file can be edited with the
- fig (Facility for Interactive Generation of figures) graphics
- editor. The output can subsequently be converted to pictex,
- PostScript, latex, epic, eepic, and tpic languages using the
- `transfig' translator.
-
- Any unrecognized options on the command line are assumed to be
- input files. The standard input is read by default only if no other
- files specified on the command line are successfully opened. A
- single dash (-) on the command line indicates the standard input is
- to be read. Each option is set and each file read in the order they
- are specified on the command line.
-
- For compatibility with pic2fig, plot2fig ignores leading white
- space in labels. Labels containing all white space are ignored.
-
- `-fn NAME'
- `-fontname NAME'
- Default: the default font of the transfig output device. This
- option sets the font for all subsequent text to NAME.
- Recognized font names are typewriter, modern, italic, bold, and
- times. In addition, courier is an alias for typewriter and
- roman is an alias for times. Note that the fonts are device
- dependent.
-
- `-fs SIZE'
- `-fontsize SIZE'
- Default: 12. This option sets the size of subsequent text to
- SIZE (in printer's points).
-
- `-h'
- `-high-byte-first'
- This option specifies that the byte ordering of two byte
- integers in the input plot file is high byte first.
-
- `-l'
- `-low-byte-first'
- This option specifies that the byte ordering of two byte
- integers in the input plot file is low byte first.
-
- `-warranty'
- `-copying'
- This option prints out the copying conditions and warranty
- information.
-
- `-signed'
- `-unsigned'
- Default: signed. This option specifies whether two byte
- integers in the input plot file are unsigned or signed.
-
- `-'
- This option specifies explicitly that the standard input should
- be read for plotting instructions.
-

-
- Tektronix 4010 output
- =====================
-
- `-H'
- `+help'
- The help option prints a summary of command line syntax, a list
- of the known font names, and version, copyright and warranty
- information. Specifying this options causes plot to ignore the
- standard input, so you must specify the option `-' if you want
- it to read the standard input as well.
-
- `-v'
- `-V'
- `+version'
- This option prints version, copyright and warranty information.
-
- `-f SIZE'
- `+fontsize SIZE'
- The fontsize options specifies the default size in printer's
- points (1/72 inch) of all text appearing in the plot. If
- unspecified, the size defaults to 14 points.
-
- `+high-byte-first'
- `+low-byte-first'
- These options force graph to use the specified byte order when
- writing out the plot file. By default the byte order is host
- dependent.
-
- `-F NAME'
- `+fontname NAME'
- The font name option specifies the name of the default font for
- all text appearing in the plot. `plot -help' prints a listing
- of the font names on the standard output. These names include
- the available builtin fonts on standard PostScript printers.
-
- `-h'
- `+high-byte-first'
- The high-byte-first option specifies explicitly that the higher
- order byte of each signed, two byte integer occurs first in the
- file. It disables determination of byte order from the file
- itself.
-
- `-l'
- `+low-byte-first'
- The low-byte-first option specifies explicitly that the lower
- order byte of each signed, two byte integer occurs first in the
- file. It disables determination of byte order from the file
- itself.
-
- `-p FILENAME'
- `+prologue FILENAME'
- The prologue option specifies the name of an alternate
- PostScript prologue FILENAME to be used in place of the default
-
- `idraw' prologue. The prologue declares procedures used to
- draw each graphic object. The default prologue was generously
- provided by John Interante and is a part of the InterViews
- distribution, version 2.5.
-
- `+copying'
- `+C'
- `+warranty'
- `+W'
- The copying and warranty options print a copy of the GNU General
- Public License on the standard error output. Included is
- conditions for copying `plot' and information on the lack of
- any warranty.
-
- `-s'
- `+signed-input'
- `-u'
- `+unsigned-input'
- The signed and unsigned options specify whether coordinates in
- the plot file are signed. By convention, coordinates are
- always signed. Some plot files do not follow this convention,
- and you can use the unsigned option to convert those files.

- Options to `psfig' for Including Figures
- ========================================
-
- `psfig' is a LaTeX command used to insert a PostScript figure into
- a document.
-
- `psfig' can be used to insert `plot2ps' generated PostScript into
- a LaTeX document. The placement of the `psfig' command tells LaTeX
- where in the document to place the PostScript, and arguments to the
- command give the name of the file containing the PostScript, and the
- desired size of the figure. Arguments are separated by commas or
- blanks, and are of the form `KEYWORD=VALUE'. The following is a
- list of valid arguments for the `psfig' command:
-
- `file=NAME'
- The file name of the PostScript figure.
-
- `height=SIZE'
- The height of the figure (eg. 3in). If you specify only a
- height or only a width, the width and height are scaled
- equally. If you specify both a width and a height the aspect
- ratio will be affected.
-
- `width=SIZE'
- The width of the figure (eg. 3in).
-
- `bbllx=COORDINATE'
- The bounding box lower left-hand x coordinate. Any PostScript
- file which conforms to the PostScript Document Structuring
- Conventions version 2.0 should contain a bounding box
- information at the head of the file. `plot2ps' output conforms
- to the version 2.0 conventions so that you should not need to
- use any of the bounding box options.
-
- `bblly=COORDINATE'
- The bounding box lower left-hand y coordinate.
-
- `bburx=COORDINATE'
- The bounding box upper right-hand x coordinate.
-
- `bbury=COORDINATE'
- The bounding box upper right-hand y coordinate.
-
- `rheight=SIZE'
- Horizontal space to reserve for the figure.
-
- `rwidth=SIZE'
- Vertical space to reserve for the figure.
-
- `clip='
- Clip the figure. `clip=' is a switch and takes no value, but
- the `=' must be present. This option is useful for including
- PostScript figures which use the size of the clipping path to
- size themselves.
-
- File: graphics.info, Node: atend.pl, Next: dvips, Prev: psfig, Up: Top
-
- A perl script for use with psfig
- ================================
-
- `atend.pl' is a perl script which moves the bounding box comment
- from the trailer to the header. Although either is legal, most
- document preparation software, such as `psfig', will only accept
- bounding box comments in the header. If you use `psfig' and the
- `-bbox' option togeather, run `atend.pl' on the output of `plot2ps'
- before importing the graphics using `psfig'.
-
- `atend.pl' can be used as a filter:
-
- echo 0 0 1 1 2 0 | spline | graph >spline.pl
- plot2ps -bbox |atend.pl - >spline.ps
-
- Or, `atend.pl' can be used to fix the output file in place:
-
- echo 0 0 1 1 2 0 | spline | graph |plot2ps -bbox >spline.ps
- atend.pl spline.ps

- `libps', a Library of Plot Functions
- ====================================
-
- Libps is a library of plot functions for drawing graphic object
- using PostScript. Before drawing any objects or using any of the
- other functions, a program should call `openpl'. Before exiting and
- after all other libps calls a program should call `closepl'.

- is adjusted to fit these ranges into the page. Note however that if
- the ranges of x and y coordinates are different the smallest scaling
- of
- the
- two is used to avoid affecting the aspect ratio of the plot. This
- means that although the plot is scaled to fit on the page, the axes
- are not stretched with respect to each other.

-
- The Plot File Format
- ====================
-
- The plot file is a set of plotting commands and data. Each
- command is a single ascii character indicating which operation is to
- be performed. The data following a command is either a newline
- terminated ascii string or several signed, two byte integers in
- binary format. For example, the command to move the current point
- to the coordinate (3,5) would be `m\000\003\000\005'.
-
- Note that the byte order of the binary representation of the
- signed, two byte integers is machine dependent, so on some machines,
- this command might appear as `m\003\000\005\000'. `plot2ps' tries
- to guess the byte order from the arguments to the `openpl' command
- and adjust the order accordingly.
-
- The following table lists each single character commands followed
- by the name of the corresponding libps function called to handle the
- data and a description of the command and data.
-
- `Command'
- Description
-
- `a'
- The arc command is followed by three pair of signed, two byte
- integers indicating the center, starting and ending points for
- a circular arc. The center becomes the the current point.
- This is equivalent to the `arc' function (*note arc::.).
-
- `c'
- The circle command is followed by three signed, two byte
- integers. The first two indicate the x and y coordinates of
- the center of the circle and the third indicates the radius of
- the circle. The center becomes the the current point. This is
- equivalent to the `circle' function (*note circle::.).
-
- `C'
- The color command is followed by three unsigned, two byte
- integer which indicate the intensity of RED, GREEN and BLUE
- components respectively of the background color. For each
- component the range of intensity is from 0 to 65535. A value
- of (0, 0, 0) represents black and (65535, 65535, 65535)
- represents white. This is equivalent to the `color' function
- (*note color::.).
-
- `e'
- The erase command is followed by no data. The erase command is
- not needed since in `idraw' and PostScript we start off with a
- blank page. For this reason the erase command does not
- actually output any PostScript. This is equivalent to the
- `erase' function (*note erase::.).
-
- `f'
- The linemod command is followed by a newline terminated string
- containing the name of the line mode (or style) for all
- subsequent lines, circles and arcs. This is equivalent to the
- `linemod' function (*note linemod::.) which describes the line
- styles and their names.
-
- `F'
- The the fontname command is followed by a newline terminated
- string containing the name of the font to be used for all
- subsequent text. This is equivalent to the `fontname' function
- (*note fontname::.).
-
- `l'
- The line command is followed by two pair of signed, two byte
- integers which indicate the starting and ending points of the
- line. The second pair becomes the the current point. This is
- equivalent to the `line' function (*note line::.).
-
- `L'
- The fill command is followed by an unsigned, two byte integer
- indicating the intensity of the fill for closed paths. A value
- of 1 represents black and a value of 0xFFFF indicates white.
- The value 0 is special in that is indicates that no solid fill
- should occur, and that the interior of the respective path is
- transparent. This is equivalent to the `fill' function (*note
- fill::.).
-
- `m'
- The move command is followed by a pair of signed, two byte
- integers containing the location of the new current point. No
- line is drawn to this point as opposed to the continue command
- (`c') which draws a line. This is equivalent to the `move'
- function (*note move::.).
-
- `n'
- The continue command is followed by pair of signed, two byte
- integers containing the coordinates of the endpoint of a line
- segment. A line is drawn from the previous current point if it
- was set using a command such as move or continue. This then
- becomes the the current point. This is equivalent to the `cont'
- function (*note cont::.).
-
- `p'
- The point command is followed by pair of signed, two byte
- integers containing the location of single point to be drawn.
- This then becomes the the current point. This is equivalent to
- the `point' function (*note point::.).
-
- `r'
- The rotate command is followed by one signed, two byte integer.
- It indicates the rotation of all subsequent text. The rotation
- is in degrees counter-clockwise from the x (horizontal) axis.
- This is equivalent to the `rotate' function (*note rotate::.).
-
- `s'
- The space command is followed by two pair of signed, two byte
- integers which indicate the the lower right-hand and upper
- left-hand corners of the range of plot coordinate space.
- `plot2ps' uses the third signed, two byte integer (the
- right-hand limit) to try to determine the byte order. This is
- equivalent to the `space' function (*note space::.) which
- describes the recognized sizes.
-
- `S'
- The fontsize command is followed by an signed, two byte integer
- containing the size in printers points of all subsequent text.
- This is equivalent to the `fontsize' function (*note
- fontsize::.).

- `t'
- The label command is followed by a newline terminated string
- contains a label which is printed at the current point. It is
- left justified and centered vertically with respect to the
- current point. The current point is then set at the end of the
- text. This is equivalent to the `label' function (*note
- label::.).
-
- `T'
- The adjusted label command is followed by two characters which
- indicate the horizontal and vertical justification respectively
- and a newline terminated string containing the label. The
- label is drawn with the specified justification and the current
- point is set at the end of the text. This is equivalent to the
- `alabel' function (*note alabel::.) which describes how to
- specify justification.
