Usage

Overview

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

This is Grace-5.99.1dev4, a preview release of the forthcoming Grace-6. Preview means that you should not use this version for a production work. Why?

•

First, the new format of project files, xgr, has not yet stabilized. In other words, anything you save with 5.99.x most probably will not load in the further 5.99.x and in the final 6.0 release without manual tweaking of some extent.

•

Another big deficiency of this release is that the old command interpreter has been removed, with no replacement on the horizon as of yet. In other words, any script-based usage of Grace is impossible now.

Options

-autoscale x|y|xy|none

Set autoscale type

-barebones

Turn off all toolbars

-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

-hardcopy

No interactive session, just print and quit

-hdevice device_name

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

[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.

-hdevice-options option_string

Set options for default hardcopy device

-install

Install private colormap

-noask

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

-source disk|pipe

Source type of next data file

-timer delay

Set allowed time slice for real time inputs to delay ms

-settype xy|xydx|...

Set the type of the next data file

-version

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

-wd path

Set the working directory

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

Specifies the browser which is used to display the Grace HTML help pages. Default is netscape

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:

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

fonts/FontDataBase - the file responsible for font configuration.
