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.
[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.
