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

              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 type
              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

              Exchange the color indices for black and white

       -safe  Run in the safe mode (default)

       -saveall file
              Save all to file

              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

              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

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.
