DESCRIPTION

   Grace  is  a  WYSIWYG  tool to make two-dimensional plots of scientific
   data.

SYNOPSIS

   grace [ option | filename ]...
   xmgrace [ option | filename ]...
   gracebat [ option | filename ]...

OPTIONS

   -autoscale x|y|xy|none
          Set autoscale type

   -barebones
          Turn off all toolbars

   -batch file
          Execute batch file on start up (i.e., after  all  other  options
          have been processed and the UI initialized)

   -block file
          Assume the data file is block data

   -bxy x:y:etc.
          Form a set from the current block data set using the current set
          type from columns given in the argument

   -datehint iso|european|us|days|seconds|nohint
          Set the hint for dates analysis

   -dpipe descriptor
          Read data from descriptor on startup

   -fixed width height
          Set canvas size fixed to width*height

   -free  Use free page layout

   -graph number
          Set the current graph number

   -graphtype xy|chart|fixed|polar|pie
          Set the type of the current graph

   -hardcopy
          No interactive session, just print and quit

   -hdevice device_name
          Set default hardcopy device. See xmgrace -version for a list  of
          supported devices.

   -install
          Install private colormap

   -legend load
          Turn the graph legend on

   -log x|y|xy
          Set the axis scaling of the current graph to logarithmic

   -maxpath length
          Set the maximal drawing path length

   -mono  Run grace in monochrome mode (affects the display only)

   -netcdf file
          Assume  data  file  is  in netCDF format. This option is present
          only if the netCDF support was compiled in

   -netcdfxy X_var Y_var
          If -netcdf was used previously, read from the netCDF file  X_var
          and  Y_var  variables and create a set.  If X_var is "null" then
          load the index of Y to X.  This option is present  only  if  the
          netCDF support was compiled in

   -noask Assume the answer is yes to all requests, if the operation would
          overwrite a file, grace will do so without prompting

   -noinstall
          Don't use private colormap

   -noprint
          In batch mode, do not print

   -nosafe

          Don't catch signals

   -npipe file
          Read data from named pipe on startup

          Assume data file is in X Y1 Y2 Y3 ...  format

   -param file
          Load parameters from file to the current graph

   -pexec string
          Interpret string as a parameter setting

   -pipe  Read data from stdin on startup

   -printfile file
          Save print output to file

   -remove
          Remove data file(s) after read

   -results file
          Write results of some data manipulations to file

   -rvideo
          Exchange the color indices for black and white

   -safe  Run in the safe mode (default)

   -saveall file
          Save all to file

   -seed value
          Integer seed for random number generator

   -settype xy|xydx|...
          Set the type of the next data file

   -source disk|pipe
          Source type of next data file

   -timer delay
          Set allowed time slice for real time inputs to delay ms

   -timestamp
          Add timestamp to plot

   -version
          Show the program version,  registered  devices  and  build  time
          configuration information.

          [DEBIAN]  Direct  PDF  output  has  been  disabled since the PDF
          library is not free software. There is an easy workaround - just
          use the epstopdf script from the tetex-bin package.

   -viewport xmin ymin xmax ymax
          Set the viewport for the current graph

   -wd path
          Set the working directory

   -world xmin ymin xmax ymax
          Set the world coordinates for the current graph

RESOURCES

   When  run  in  the  GUI  mode, the interface is a subject to X resource
   settings.
          Please refer to the User's Guide for a list of important ones.

ENVIRONMENT

   GRACE_HOME
          Specifies the directory  where  the  Grace  docs  and  libs  are
          stored. Default is /usr/local/grace

   GRACE_HELPVIEWER
          The  shell command to run an HTML viewer for on-line browsing of
          the help documents. Must include at least one instance  of  "%s"
          which  will be replaced with the actual URL by Grace. Default is
          mozilla %s

   GRACE_EDITOR
          Specifies the editor which is used  to  edit  sets.  Default  is
          xterm -e vi

   GRACE_PRINT_CMD
          The print command.

   GRACE_FFTW_RAM_WISDOM
          and GRACE_FFTW_WISDOM_FILE A flag (0 or 1) and a file name which
          determine whether a FFT should use `wisdom' when using the  FFTW
          libraries.

FILES

   In  many cases, when Grace needs to access a file given with a relative
   pathname, it searches for the file along the following path:
    ./pathname:./.grace/pathname:~/.grace/pathname:$GRACE_HOME/pathname

   The following files are of a special importance:

   gracerc - init file loaded upon start up.

   templates/Default.agr - the default template,  loaded  whenever  a  new
   project is started.

   fonts/FontDataBase - the file responsible for font configuration.
