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: Disable safe mode
-nosigcatch: Don't catch signals
-npipe file: Read data from named pipe on startup
-nxy file: 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.
-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
-usage|-help: This message

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.
