remove xgraph from ngspice distribution.

ngspice supports gnuplot instead.
30 year old legacy code, not maintained.
Does not compile on MS Windows,
compiles on Cygwin, but xgraph.exe crahes immediately.
Lots of compiler warnings.

-XGRAPH INSTALLATION
-===================
-
-
-Quick Start
------------
-
-- download the source code
-- extract tar file with gzip (gnu zip, not pkzip) and tar
-	(typically "gunzip <xgraph.tar.gz | tar xvf -")
-- run "./configure"
-	see the file README.CONFIGURE for 
-- run "make"
-- run "make install"
-
-To install xgraph in a special location (perhaps if you don't have
-root access), or if you're not familiar with GNU configure, see "Basic
-Installation" below.
-
-If you have installation problems or questions, check:
-
-	<http://www-mash.cs.berkeley.edu/ns/ns-problems.html#xgraph>
-
-BEFORE posting to the mailing list.  Mailing list info can be found at
-the xgraph web page.
-
-
-Xgraph-specific configure options
----------------------------------
-
-Use
-	--with-additional-includes=/path/to/includes
-and
-	--with-additional-libs=/path/to/libs
-
-if configure can't find particular includes or libraries on your
-system.
-
-
-Basic Installation
-==================
-
-   These are generic installation instructions.
-
-   The `configure' shell script attempts to guess correct values for
-various system-dependent variables used during compilation.  It uses
-those values to create a `Makefile' in each directory of the package.
-It may also create one or more `.h' files containing system-dependent
-definitions.  Finally, it creates a shell script `config.status' that
-you can run in the future to recreate the current configuration, a file
-`config.cache' that saves the results of its tests to speed up
-reconfiguring, and a file `config.log' containing compiler output
-(useful mainly for debugging `configure').
-
-   If you need to do unusual things to compile the package, please try
-to figure out how `configure' could check whether to do them, and mail
-diffs or instructions to the address given in the `README' so they can
-be considered for the next release.  If at some point `config.cache'
-contains results you don't want to keep, you may remove or edit it.
-
-   The file `configure.in' is used to create `configure' by a program
-called `autoconf'.  You only need `configure.in' if you want to change
-it or regenerate `configure' using a newer version of `autoconf'.
-
-The simplest way to compile this package is:
-
-  1. `cd' to the directory containing the package's source code and type
-     `./configure' to configure the package for your system.  If you're
-     using `csh' on an old version of System V, you might need to type
-     `sh ./configure' instead to prevent `csh' from trying to execute
-     `configure' itself.
-
-     Running `configure' takes awhile.  While running, it prints some
-     messages telling which features it is checking for.
-
-  2. Type `make' to compile the package.
-
-  3. Optionally, type `make check' to run any self-tests that come with
-     the package.
-
-  4. Type `make install' to install the programs and any data files and
-     documentation.
-
-  5. You can remove the program binaries and object files from the
-     source code directory by typing `make clean'.  To also remove the
-     files that `configure' created (so you can compile the package for
-     a different kind of computer), type `make distclean'.
-
-Compilers and Options
-=====================
-
-   Some systems require unusual options for compilation or linking that
-the `configure' script does not know about.  You can give `configure'
-initial values for variables by setting them in the environment.  Using
-a Bourne-compatible shell, you can do that on the command line like
-this:
-     CC=c89 CFLAGS=-O2 LIBS=-lposix ./configure
-
-Or on systems that have the `env' program, you can do it like this:
-     env CPPFLAGS=-I/usr/local/include LDFLAGS=-s ./configure
-
-Compiling For Multiple Architectures
-====================================
-
-   You can compile the package for more than one kind of computer at the
-same time, by placing the object files for each architecture in their
-own directory.  To do this, you must use a version of `make' that
-supports the `VPATH' variable, such as GNU `make'.  `cd' to the
-directory where you want the object files and executables to go and run
-the `configure' script.  `configure' automatically checks for the
-source code in the directory that `configure' is in and in `..'.
-
-   If you have to use a `make' that does not supports the `VPATH'
-variable, you have to compile the package for one architecture at a time
-in the source code directory.  After you have installed the package for
-one architecture, use `make distclean' before reconfiguring for another
-architecture.
-
-Installation Names
-==================
-
-   By default, `make install' will install the package's files in
-`/usr/local/bin', `/usr/local/man', etc.  You can specify an
-installation prefix other than `/usr/local' by giving `configure' the
-option `--prefix=PATH'.
-
-   You can specify separate installation prefixes for
-architecture-specific files and architecture-independent files.  If you
-give `configure' the option `--exec-prefix=PATH', the package will use
-PATH as the prefix for installing programs and libraries.
-Documentation and other data files will still use the regular prefix.
-
-   In addition, if you use an unusual directory layout you can give
-options like `--bindir=PATH' to specify different values for particular
-kinds of files.  Run `configure --help' for a list of the directories
-you can set and what kinds of files go in them.
-
-Optional Features
-=================
-
-   Some packages pay attention to `--enable-FEATURE' options to
-`configure', where FEATURE indicates an optional part of the package.
-They may also pay attention to `--with-PACKAGE' options, where PACKAGE
-is something like `gnu-as' or `x' (for the X Window System).  The
-`README' should mention any `--enable-' and `--with-' options that the
-package recognizes.
-
-Sharing Defaults
-================
-
-   If you want to set default values for `configure' scripts to share,
-you can create a site shell script called `config.site' that gives
-default values for variables like `CC', `cache_file', and `prefix'.
-`configure' looks for `PREFIX/share/config.site' if it exists, then
-`PREFIX/etc/config.site' if it exists.  Or, you can set the
-`CONFIG_SITE' environment variable to the location of the site script.
-A warning: not all `configure' scripts look for a site script.
-
-Operation Controls
-==================
-
-   `configure' recognizes the following options to control how it
-operates.
-
-`--cache-file=FILE'
-     Use and save the results of the tests in FILE instead of
-     `./config.cache'.  Set FILE to `/dev/null' to disable caching, for
-     debugging `configure'.
-
-`--help'
-     Print a summary of the options to `configure', and exit.
-
-`--quiet'
-`--silent'
-`-q'
-     Do not print messages saying which checks are being made.  To
-     suppress all normal output, redirect it to `/dev/null' (any error
-     messages will still be shown).
-
-`--srcdir=DIR'
-     Look for the package's source code in directory DIR.  Usually
-     `configure' can determine that directory automatically.
-
-`--version'
-     Print the version of Autoconf used to generate the `configure'
-     script, and exit.
-
-`configure' also accepts some other, not widely useful, options.

xgraph/README.ANNOUNCE

@@ -1,84 +0,0 @@
-
-A new version of xgraph is now available.  Xgraph is a popular
-two-dimensional plotting program that accepts data in a form similar
-to the unix program graph and displays line graphs, scatter plots, or
-bar charts on an X11 display.  These graphs are fully annotated with a
-title, axis numbering and labels, and a legend.  Zooming in on regions
-of a graph is supported.  The program can automatically generate
-hardcopy output to Postscript printers and HPGL plotters.  A new
-option allows xgraph output to be directly pasted into idraw for
-further annotation.
-
-This program is NOT a widget.  It is a stand-alone program written at
-the Xlib level and should run on any machine with a reasonable
-implementation of X11 release 3 or later.  The source for the program
-is available through anonymous ftp to shambhala.Berkeley.EDU
-(128.32.132.54):
-
-	% ftp shambhala.Berkeley.EDU
-	Name: anonymous
-	Password: <anything non-null>
-	ftp> cd pub
-	ftp> binary
-	ftp> get xgraph-11.tar.Z
-	ftp> quit
-	% uncompress xgraph-11.tar.Z
-	% tar xf xgraph-11.tar
-
-This will create a directory called xgraph-11.  In that directory
-you will find a file called README.INSTALL that contains directions
-for building the program.  I plan to submit the sources to the
-moderator of comp.sources.x after I have tested the program under X11
-release 4 (meaning a few weeks after the X Consortium releases the
-distribution).
-
-Those who do not have ftp access can obtain the source for xgraph
-using a mail archive system I have installed on dent.Berkeley.EDU
-(courtesy of Brian Reid at Digital).  An example is given below:
-
-	To: ucbvax!dent!archive-server
-	Subject: send programs xgraph.shar.01 xgraph.shar.02
-
-	send programs xgraph.shar.03 xgraph.shar.04 xgraph.shar.05
-	send programs xgraph.shar.06 xgraph.shar.07 xgraph.shar.08
-
-The archive server will send you these files as time and load permits.
-They are standard shell archives and can be unpacked by running them
-through /bin/sh (in order).  If you would like to know more about the
-mail server, send a message with a subject of "help".  I am afraid I
-am no mail wizard so I cannot help you determine a path to dent.
-
-For those familar with xgraph, the most important changes are
-summarized below:
-
-- A new data reader has been written that allows discontinuous data in
-  each data set.  Also, nearly all of the display options for xgraph
-  can be set in the data file.  The reader is also more forgiving
-  about blank lines and excess white space.
-
-- A new option has been added to the Postscript hardcopy facility to
-  allow xgraph output to be included in other documents using psfig.
-  As mentioned above, xgraph output can be imported into idraw for
-  further annotation if necessary.
-
-- I received lots of complaints about the way xgraph obtains fonts and
-  visuals.  The new xgraph uses a much simpler scheme to obtain these
-  resources and has fall back code to insure it will run in almost any
-  situation.
-
-- Options handling has been cleaned up substantially.  Xgraph options
-  can now be specified as X resources (~/.Xdefaults), in the data
-  file, or on the command line.
-
-- Drawing is somewhat faster on some servers due to a better choice of
-  initial defaults.
-
-Please send all bug reports, questions, comments or suggestions to
-the electronic address below.

xgraph/README.GENERAL

@@ -1,74 +0,0 @@
-
-This directory contains source for the X11 version of xgraph,  a
-two-dimensional data plotting program.  Those familar with the X10
-version of this program will find that is completely compatible.
-However,  there are a few important notes and changes you should
-be aware of:
-
-1. The program was developed and tested on X11 release 3 on a
-   color VAXstation GPX and on a color DECstation 3100.  It should
-   work on most other servers without change but has not been tested
-   on these other configurations.  If you have problems,  please send
-   a note to:
-
-	davidh@ic.Berkeley.EDU
-	        or
-	...!ucbvax!ucbcad!davidh
-
-2. This version includes an improved hardcopy facility.  
-   An additional option, "Include in Document", has been added since
-   the first X11 release.  A new output type, Idraw, has also been
-   added.  See the manual page for details about the hardcopy dialog.
-
-3. There are several changes to the input format for xgraph.  However,
-   the new format is compatible with the old and there should be no
-   problem running xgraph with old data sets.  The new form allows
-   discontinuous data in data sets (using the "move" operator),
-   parameter specification using a format similar to that found in the
-   ~/.Xdefaults file, and comments.  See the manual page for details.
-
-4. In some cases,  xgraph uses dashed lines to distinguish different
-   data sets.  Some servers are notoriously slow at rendering dashed
-   lines.  Be prepared for a significantly reduced performance on
-   those servers.
-
-5. Xgraph now uses software clipping to clip data to its display
-   windows.  This means you should be able to zoom in much farther
-   on large data sets than was possible under the X10 version.
-
-6. Xgraph used to use some rather sophisticated heuristics to handle
-   visuals and colormaps.  Due to complaints, I have removed these
-   heuristics.  Xgraph will display on whatever screen is specified in
-   the DISPLAY environment variable or on the command line.
-
-7. I plan to add full ICCCM support when X11 release 4 becomes
-   available.  In the meantime, the program should work under most
-   window mangers (it is somewhat conformant already).
-
-8. As a follow-on to (7),  note that the operation of the program
-   is heavily influenced by your choice of window managers.  Focus
-   based window managers (like dxwm from Digital) will require you
-   to set focus in the text input slots of the hardcopy dialog box.
-
-9. Many people have sent me notes about the state of code of xgraph.
-   Xgraph was constructed initially as a challenge from another
-   programmer here at Berkeley.  The first version of the program was
-   written in an afternoon.  Since then, the program has "evolved"
-   quite dramatically.  Since this is not my primary work, I generally
-   tacked on features quickly as the need became apparent.  Some day,
-   I would truely like to rewrite it.  Until then, please bear with
-   me.
-
-10. Since xgraph has become quite popular,  those in positions of power
-   have recommended I add the standard UC Berkeley copyright notice
-   to this software.  See copyright.h for details.
-
-11. Many people have sent me suggestions and comments.  Some have
-   written new code or sent patches to fix problems.  I greately 
-   appreciate these contributions.  Special thanks go to Beorn Johnson 
-   and Alan Kramer for the idraw output code.

-/*
- * Hardcopy Interface for Xgraph
- *
- * Major differences from first version:
- *   A flags argument has been added to xg_init().  This new argument
- *   is used to specify a new binary option: D_DOCU.  See below
- *   for details.
- *
- *   Four new parameters are passed to the device initialization routine:
- *   title_family, title_size, axis_family, and axis_size.  See the 
- *   description of xg_init() for details.
- *   
- *   Clipping is done automatically by xgraph.  The xg_clip() routine
- *   is obsolete.
- *
- *   The xg_line() routine has become the xg_seg() routine.  It now
- *   draws segments rather than a series of lines.  
- * 
- *   A new field (max_segs) in the device structure now specifies 
- *   the maximum number of segments the device can handle in a group.

-/*
- * Adding an output device to xgraph
- *
- * Step 1
- *   Write versions of the following routines for your device:
- *   xg_init(), xg_text(), xg_seg(), xg_dot(), and xg_end().
- *   The interface and function of these routines are described
- *   in detail below.  These routines should be named according
- *   to your device.  For example,  the initialization routine
- *   for the Postscript output device is psInit().  Also,  name
- *   your source file after your device (e.g. the postscript
- *   routines are in the file ps.c).  Instructions continue
- *   after the description of the interface routines.
- *
- *   The definitions below are quoted here as a convenience.  In
- *   your output module, you can include "xgout.h" to obtain these

- * This routine is called by xgraph just before drawing is to
- * begin.  The desired size of the plot is given by `width'
- * and `height'.  The parameters `title_family', `title_size',
- * `axis_family', and `axis_size' specify the names of the
- * title and axis fonts and their vertical sizes (in points).
- * These parameters can be ignored if your device does not
- * support multiple fonts.  The `flags' argument specifies
- * certain binary flags to the output routines.  These
- * flags are:
- *  D_DOCU:
- *      If this flag is set,  it indicates the user has specified that
- *	the output will be included in some larger document.  Devices
- *	may choose to use this information to produce output that
- *	can be integrated into documents with less effort.  For example,
- *	the Postscript output routines produce bounding box information
- *	when this flag is set.
- * The routine should fill in all of the fields of `out_info' with 
- * appropriate values.  The values are described below:
- *  area_w, area_h:  
- * 	Size of the drawing space in device coordinates.
- *	This should take in account the requested area
- *	given by `width', and `height'.
- *  bdr_pad:  
- * 	Xgraph will leave this number of device coordinates around
- *	all of the outer edges of the graph.
- *  axis_pad: 
- *	Additional space around axis labels (in devcoords)
- *	so that the labels do not appear crowded.
- *  legend_pad:
- *	Space (in devcoords) from the top of legend text to
- *	the representative line drawn above the legend text.
- *  tick_len:    
- *	Size of a tick mark placed on axis (in devcoords)
- *  axis_width:  
- *	An estimate of the width of a large character in
- *      the axis font (in devcoords).  This can be an overestimate.  An
- *      underestimate may produce bad results.
- *  axis_height: 
- *	An estimate of the height of a large character in
- *      the axis labeling font (in devcoords).
- *  title_width, title_height:  
- *	Same as above except for the title font.
- *  max_segs:
- *	Due to buffering constraints,  some devices may not be able to
- *	handle massive segment lists.  This parameter tells xgraph not
- *	to send more than `max_segs' segments in one request.
- * Output to the device should be written to the stream `strm'.
- * The functions are described individually below.  After filling
- * in the parameters and setting the function pointers,  the routine
- * should initialize its drawing state and store any extra needed
- * information in `user_state'.  This value will be passed to all
- * other routines during the drawing sequence.  If the device
- * cannot initialize,  it should return a zero status and fill
- * `errmsg' with an informative error message.

-This file contains instructions for building the X11 version of xgraph.
-When unpacked,  the source is distributed in three directories:
-
-	xgraph-11		Source for the program
-	xgraph-11/bitmaps	Bitmaps used for cursors and markers
-	xgraph-11/examples	Sample data for trying out the program
-
-First, you should examine the file hard_devices.c.  This file lists
-the default hardcopy parameters for each hardcopy output device.  Some
-of these defaults are site-specific and should be taylored to your
-site.  For example, at our site, the default HPGL plotter is called
-"paper" and the default Postscript printer is called "lps40".  You can
-change these names in this file.  See hard_devices.h for a description
-of the initialization fields.
-
-If you do not like the default values for xgraph options, you can
-change these by editing the default values as listed on the third page
-in xgraph.c.  Remember that changing these values changes the default
-behaviour for everyone running the program.  Personal preference
-should be left for specification in the user's Xresources or Xdefaults
-file.
-
-An Imakefile is provided for compiling the program in an X11 release 3
-source tree.  If you have such a source tree, type the following in
-the xgraph-11 directory:
-
-	% make TOP=<source-tree-top>
-
-where <source-tree-top> is the top level directory of the X11 release
-3 source tree.  If you don't have an X11 source tree but you have all
-of the X libraries and include files installed in "standard
-locations", type the following the in the xgraph-11 directory:
-
-	% make -f Makefile.std
-
-Either of these commands will produce an executable xgraph in the
-xgraph-11 directory.  If you are installing the program in an X11
-source tree, you can use the following to install the program and
-manual page in the proper locations:
-
-	% make TOP=<source-tree-top> install
-	% make TOP=<source-tree-top> install.man
-
-You might want to try these commands with the "-n" option once to make
-sure the program and manual page are installed in the proper
-directories.  If they aren't, you may want to change the DESTDIR
-variable and try again.  If you really need to change the Makefile
-options, you can generate a new Makefile from the Imakefile using
-imake as provided on the X11 release tape.
-
-Several example data sets are provided in the xgraph-11/examples
-directory.  Try the following to check out xgraph:
-
-	% xgraph examples/xgtest.xg
-
-This should produce a graph with a series of parabolic curves.
-
-Other documentation files are included.  A summary of these
-files is given below:

xgraph/README.NEWFEATURES

@@ -1,43 +0,0 @@
-This code is essentially XGraph release 11.4, with some modifications
-which were made for use by the NCSA Relativity group.
-These modifications were made by Paul Walker, and he should be
-contacted at the below address if you have any problems/questions
-regarding these features.
-
-1.	Animation.  XGraph will now do a *very* crude animation of
-	your data sets.  It occasionally has problems with refreshes
-	and will consequently run your animation three of four times.
-	Consider this an undocumented feature!  You can adjust the
-	speed of the animation with the -dl option.  I find "2" works
-	well on a sparc displaying on MacX, "5" on a sparc on its
-	own display, and "10" on an SGI or RS6K on its own display.
-	Remeber, this animation is not being advertised as anything
-	other than very crude, so if you are looking for production
-	quality video, turn elsewhere.  We find it useful as it will
-	quickly generate animation which shows time evolution. 
-
-2.	Differentation.  You can press the "Derivative" button to
-	see the first and second derivatives of your data set.  The
-	method is a standard centered difference.  You cannot display
-	higher than second derivatives.  Animation, zooming, etc...
-	work in each of the derivative windows.  Endpoints are found
-	linearly interpolating inner values to ends, so pay them
-	little heed!
-
-3.	New Color Map.  We couldn't differentiate the colors once we
-	got past yellow, so we created a new color map.  If you don't
-	like it, look in init.c for the variable "defColors" and 
-	comment out the new one, replacing it with the commented
-	old one.  Of course, you are free to insert your own choices
-	here also ... Just use standard X color names.

-#
-# Of course, Automake must honor this variable whenever it calls a

-# therefore $ac_aux_dir as well) can be either absolute or relative,
-# depending on how configure is run.  This is pretty annoying, since

-#    fails when called from a subdirectory in a VPATH build with
-#          a relative $ac_aux_dir
-#
-# The reason of the latter failure is that $top_srcdir and $ac_aux_dir
-# are both prefixed by $srcdir.  In an in-source build this is usually
-# harmless because $srcdir is `.', but things will broke when you
-# start a VPATH build or use an absolute $srcdir.
-#
-# So we could use something similar to $top_srcdir/$ac_aux_dir/missing,

-# This will work as long as MISSING is not called from configure, because
-# unfortunately $(top_srcdir) has no meaning in configure.
-# However there are other variables, like CC, which are often used in
-# configure, and could therefore not use this "fixed" $ac_aux_dir.

- * This routine is called by xgraph just before drawing is to
- * begin.  The desired size of the plot is given by `width'
- * and `height'.  The parameters `title_family', `title_size',
- * `axis_family', and `axis_size' specify the names of the
- * title and axis fonts and their vertical sizes (in points).
- * These parameters can be ignored if your device does not
- * support multiple fonts.  Binary flags are specified in
- * the `flags' field.  These include:
- *  D_DOCU:
- *      If this flag is set,  it indicates the user has specified that
- *	the output will be included in some larger document.  Devices
- *	may choose to use this information to produce output that
- *	can be integrated into documents with less effort.  For example,
- *	the Postscript output routines produce bounding box information
- *	when this flag is set.
- * The routine should fill in all of the fields of `out_info' with
- * appropriate values.  The values are described below:
- *  area_w, area_h:
- * 	Size of the drawing space in device coordinates.
- *	This should take in account the requested area
- *	given by `width', and `height'.
- *  bdr_pad:
- * 	Xgraph will leave this number of device coordinates around
- *	all of the outer edges of the graph.
- *  axis_pad:
- *	Additional space around axis labels (in devcoords)
- *	so that the labels do not appear crowded.
- *  legend_pad:
- *	Space (in devcoords) from the top of legend text to
- *	the representative line drawn above the legend text.
- *  tick_len:
- *	Size of a tick mark placed on axis (in devcoords)
- *  axis_width:
- *	An estimate of the width of a large character in
- *      the axis font (in devcoords).  This can be an overestimate.  An
- *      underestimate may produce bad results.
- *  axis_height:
- *	An estimate of the height of a large character in
- *      the axis labeling font (in devcoords).
- *  title_width, title_height:
- *	Same as above except for the title font.
- *  max_segs:
- *	Due to buffering constraints,  some devices may not be able to
- *	handle massive segment lists.  This parameter tells xgraph not
- *	to send more than `max_segs' segments in one request.
- * Output to the device should be written to the stream `strm'.
- * The functions are described individually below.  After filling
- * in the parameters and setting the function pointers,  the routine
- * should initialize its drawing state and store any extra needed
- * information in `user_state'.  This value will be passed to all
- * other routines during the drawing sequence.  If the device
- * cannot initialize,  it should return a zero status and fill
- * `errmsg' with an informative error message.

-.TH XGRAPH 1 "December, 1989"
-.SH NAME
-xgraph \- Draw a graph on an X11 Display
-.SH SYNOPSIS
-.B xgraph
-[ options ] [[-geometry |=]WxH+X+Y ] [ -display host:display.screen ] [ file ... ]
-.SH DESCRIPTION
-The 
-.I xgraph
-program draws a graph on an X display given data read from either
-data files or from standard input if no files are specified.
-It can display up to 64 independent data sets using different colors
-and/or line styles for each set.
-It annotates the graph with a title,  axis labels,  grid lines or tick
-marks, grid labels,  
-and a legend.
-There are options to control the appearance of most components of
-the graph.
-.PP
-The input format is similar to
-.I graph(1G)
-but differs slightly.
-The data consists of a number of
-.I "data sets."
-Data sets are separated by a blank line.
-A new data set is also
-assumed at the start of each input file.
-A data set consists of an ordered list of points of the form "{directive} X Y".
-The directive is either "draw" or "move" and can be omitted.
-If the directive is "draw", a line will be drawn between the previous
-point and the current point (if a line graph is chosen).
-Specifying a "move" directive tells xgraph not to draw a line between
-the points.
-If the directive is omitted, "draw" is assumed for all points in
-a data set except the 
-first point where "move" is assumed.
-The "move" directive is used most often to allow discontinuous data
-in a data set.
-The name of a data set can be specified by 
-enclosing the name in double quotes on a line by itself in the
-body of the data set.  The trailing double quote is optional.
-Overall graphing options for the graph can be specified in data
-files by writing lines of the form "<option>: <value>".  The
-option names are the same as those used for specifying X 
-resources (see below). The option and value must be separated by at
-bleast one space.
-An example input file with three data sets is shown below.  Note
-that set three is not named, set two has discontinuous data,
-and the title of the graph is specified near the top of the file.

-.fi
-.PP
-After
-.I xgraph
-has read the data,  it will create a new window to graphically
-display the data.
-The interface used to specify the size and location of this window depends
-on the window manager currently in use.
-Refer to the reference manual of the window manager for details.
-.PP
-Once the window has been opened,  all of the data sets will be displayed
-graphically (subject to the options explained below) with a legend in 
-the upper right corner of the screen.
-To zoom in on a portion of the graph,  depress a mouse button in
-the window and sweep out a region.
-.I xgraph
-will then open a new window looking at just that portion of the graph.
-.I xgraph
-also presents three control buttons in the upper left corner of
-each window:
-.I Close,
-.I Hardcopy,
-and
-.I About.
-Windows are closed by depressing a mouse button while the mouse
-cursor is inside the
-.I Close
-button.  Typing EOF (control-D) in a window also closes that window.
-Depressing a mouse button while the mouse cursor is in the
-.I Hardcopy
-button causes a dialog to appear asking about hardcopy (printout)
-options.  These options are described below:
-.IP "Output Device"
-Specifies the type of the output device (e.g. "HPGL", "Postscript", etc).
-An output device is chosen by depressing the mouse inside its name.
-The default values of other fields will change when you select a
-different output device.
-.IP "Disposition"
-Specifies whether the output should go directly to a device
-or to a file.  Again,  the default values of other fields will change
-when you select a different disposition.
-.IP "File or Device Name"
-If the disposition is "To Device",  this field specifies the device
-name.
-A device name is the same as the name given for the -P command
-of lpr(1).
-If the disposition is "To File",  this field specifies the name
-of the output file.
-.IP "Maximum Dimension"
-This specifies the maximum size of the plot on the hardcopy
-device in centimeters.
-.I xgraph
-takes in account the aspect ratio of the plot on the screen
-and will scale the plot so that the longer side of the plot
-is no more than the value of this parameter.
-If the device supports it,  the plot may also be rotated on the page
-based on the value of the maximum dimension.
-.IP "Include in Document"
-If selected, this option causes
-.I xgraph
-to produce harcopy output that is suitable for inclusion in other
-larger documents.
-As an example,  when this option is selected the Postscript output 
-produced by xgraph will have a bounding box suitable for use with
-psfig.
-.IP "Title Font Family"
-This field specifies the name of a font to use when drawing
-the graph title.  Suitable defaults are initially chosen for
-any given hardcopy device.
-The value of this field is hardware specific -- refer to
-the device reference manual for details.
-.IP "Title Font Size"
-This field specifies the desired size of the title fonts in points
-(1/72 of an inch).  
-If the device supports scalable fonts,  the
-font will be scaled to this size.
-.IP "Axis Font Family and Axis Font Size"
-These fields are like
-.I "Title Font Family"
-and
-.I "Title Font Size"
-except they specify values for the font
-.I xgraph
-uses to draw axis labels, and legend descriptions.
-.IP "Control Buttons"
-After specifing the parameters for the plot,  the "Ok" button causes
-.I xgraph
-to produce a hardcopy.
-Pressing the "Cancel" button will abort the hardcopy operation.
-Depressing the
-.I About
-button causes Xgraph to display a window containing the version of
-the program and an electronic mailing address for the author
-for comments and suggestions.
-.PP
-.I xgraph
-accepts a large number of options most of which can be specified
-either on the command line, in the user's .Xdefaults or .Xresources file, 
-or in the data files themselves.
-A list of these options is given below.  The command line
-option is specified first with its X default or data file name (if any) 
-in parenthesis afterward.
-The format of the option in the X defaults file is "program.option: value"
-where program is the program name (xgraph) and the option name is the
-one specified below.
-Option specifications in the data file are similar to the X defaults file
-specification except the program name is omitted.
-.TP
-.B  \-geometry WxH+X+Y or \=WxH+X+Y (Geometry)
-Specifies the initial size and location of the xgraph window.
-.TP
-.B  \-<digit> <name>
-These options specify the data set name for the corresponding data set.
-The digit should be in the range '0' to '63'.
-This name will be used in the legend.
-.TP
-.B  \-bar (BarGraph)
-Specifies that vertical bars should be drawn from the data points to
-a base point which can be specified with -brb.  Usually,  the -nl
-flag is used with this option.  The point itself is located at
-the center of the bar.
-.TP
-.B  \-bof (BarGraph)
-Offset the bars for additional datasets by the specified amount.
-.TP 
-.B  \-device <name>
-Set the output device for xgraph. The default is 'X'; other valid
-devices are 'ps', 'hpgl', 'idraw' and tgif.
-.TP
-.B  \-o <filename> \-O <filename>
-Set the output file name for postscript, hpgl and idraw devices.
-Files created with -O can be used other documents, and files generated
-with -o can be printed directly.
-.TP
-.B  \-P<printername>
-Set the printer name for postscript or hpgl devices. This and the -o or -O
-option are mutually exclusive.
-.TP 
-.B \-stk
-Stack elements coming from different datasets, instead of plotting them
-from the same baseline. Datasets must match exactly.
-.TP 
-.B \-fitx
-Translate and scale the x data from all datasets to fit [0..1].
-.B \-fity
-Translate and scale the y data from all datasets to fit [0..1].
-.TP
-.B \-scale <factor>
-Output scale factor for postscript, hpgl and idraw devices. The default
-is 1.0, and 0.5 will generate a 50% reduced plot.
-.TP
-.B \-fmtx <printf-format> \-fmty <printf-format>
-Use the format specified to generate the legents for the x or y axis.
-.TP
-.B  \-bb (BoundBox)
-Draw a bounding box around the data region.  This is very useful
-if you prefer to see tick marks rather than grid lines (see -tk).
-.TP
-.B  \-bd <color> (Border)
-This specifies the border color of the
-.I xgraph
-window.
-.TP
-.B  \-bg <color> (Background)
-Background color of the
-.I xgraph
-window.
-.TP
-.B  \-brb <base> (BarBase)
-This specifies the base for a bar graph.  By default,  the base is zero.
-.TP
-.B  \-brw <width> (BarWidth)
-This specifies the width of bars in a bar graph.  The amount is specified
-in the user's units.  By default,  a bar one pixel wide is drawn.
-.TP
-.B  \-bw <size> (BorderSize)
-Border width (in pixels) of the
-.I xgraph
-window.
-.TP
-.B  \-db (Debug)
-Causes xgraph to run in synchronous mode and prints out the values
-of all known defaults.
-.TP
-.B  \-fg <color> (Foreground)
-Foreground color.  This color is used to draw all text and the normal
-grid lines in the window.
-.TP
-.B  \-gw (GridSize)

-A font name may be specified exactly (e.g. "9x15" or 
-"-*-courier-bold-r-normal-*-140-*") or in an abbreviated form: <family>-<size>.
-The family is the family name (like helvetica) and the size is the font
-size in points (like 12).  The default for this parameter is "helvetica-12".
-.TP
-.B  \-lnx (LogX)
-Specifies a logarithmic X axis.  Grid labels represent powers of ten.
-.TP
-.B  \-lny (LogY)
-Specifies a logarithmic Y axis.  Grid labels represent powers of ten.
-.TP
-.B  \-lw width (LineWidth)
-Specifies the width of the data lines in pixels.  The default is zero.
-.TP
-.B  \-lx <xl,xh> (XLowLimit, XHighLimit)
-This option limits the range of the X axis to the specified
-interval.  This (along with -ly) can be used to "zoom in" on a particularly
-interesting portion of a larger graph.
-.TP
-.B  \-ly <yl,yh> (YLowLimit, YHighLimit)
-This option limits the range of the Y axis to the specified
-interval.
-.TP
-.B  \-m (Markers)
-Mark each data point with a distinctive marker.
-There are eight distinctive markers used by xgraph.
-These markers are assigned uniquely to each different line style on
-black and white machines and varies with each color on color machines.
-.TP
-.B  \-M (StyleMarkers)
-Similar to -m but markers are assigned uniquely to each eight consecutive
-data sets (this corresponds to each different line style on color machines).
-.TP
-.B  \-nl (NoLines)
-Turn off drawing lines.  When used with -m, -M, -p, or -P this can be used to
-produce scatter plots.  When used with -bar,  it can be used to
-produce standard bar graphs.
-.TP
-.B  \-ng (NoLegend)
-Turn off drawing Legends. Can be used to increase the drawing area.
-.TP
-.B  \-p (PixelMarkers)
-Marks each data point with a small marker (pixel sized).  This is
-usually used with the -nl option for scatter plots.
-.TP
-.B  \-P (LargePixels)
-Similar to -p but marks each pixel with a large dot.
-.TP
-.B  \-rv (ReverseVideo)
-Reverse video.  On black and white displays,  this will invert
-the foreground and background colors.  
-The behaviour on color displays is undefined.
-.TP
-.B  \-t <string> (TitleText)
-Title of the plot.  This string is centered at the top of the graph.
-.TP
-.B  \-tf <fontname> (TitleFont)
-Title font.  This is the name of the font to use for the graph title.
-A font name may be specified exactly (e.g. "9x15" or 
-"-*-courier-bold-r-normal-*-140-*") or in an abbreviated form: <family>-<size>.
-The family is the family name (like helvetica) and the size is the font
-size in points (like 12).  The default for this parameter is "helvetica-18".
-.TP
-.B  \-tk (Ticks)
-This option causes
-.I xgraph
-to draw tick marks rather than full grid lines.  The -bb option
-is also useful when viewing graphs with tick marks only.
-.TP
-.B  \-tkax (Tick Axis)
-When tick marks are enabled, plot the axes.
-.TP
-.B  \-x <unitname> (XUnitText)
-This is the unit name for the X axis.  Its default is "X".
-.TP
-.B  \-y <unitname> (YUnitText)
-This is the unit name for the Y axis.  Its default is "Y".
-.TP
-.B  \-zg <color> (ZeroColor)
-This is the color used to draw the zero grid line.
-.TP
-.B  \-zw <width> (ZeroWidth)
-This is the width of the zero grid line in pixels.
-.PP
-Some options can only be specified in the X defaults file or in the
-data files.  These options are described below:
-.TP
-.B <digit>.Color
-Specifies the color for a data set.  Eight independent colors can
-be specified.  Thus,  the digit should be between '0' and '7'.
-If there are more than eight data sets,  the colors
-will repeat but with a new line style (see below).
-.TP
-.B <digit>.Style
-Specifies the line style for a data set.  A string of ones
-and zeros specifies the pattern used for the line style.
-Eight independent line styles can be specified.  Thus,  the
-digit should be between '0' and '7'.  If there are more
-than eight data sets,  these styles will be reused.  On color
-workstations,  one line style is used for each of eight colors.
-Thus,  64 unique data sets can be displayed.
-.TP
-.B Device
-The default output form presented in the hardcopy dialog (i.e. "Postscript",
-"HPGL", etc).
-.TP
-.B Disposition
-The default setting of whether output goes directly to a device or to a file.  
-This must be one of the strings "To File" or "To Device".
-.TP
-.B FileOrDev
-The default file name or device string in the hardcopy dialog.
-.TP
-.B ZeroWidth
-Width,  in pixels,  of the zero grid line.
-.TP
