Grace is a WYSIWYG 2D plotting tool for the X Window System and M*tif,
successor of ACE/gr (Xmgr). A few of its features are:
* User defined scaling, tick marks, labels, symbols, line styles,
colors.
* Batch mode for unattended plotting.
* Read and write parameters used during a session.
* Polynomial regression, splines, running averages, DFT/FFT,
cross/auto-correlation.
* Exports high-resolution graphics to (E)PS, PDF, MIF, and SVG
formats
* Supports cross-platform PNM, JPEG and PNG formats
While grace has a convenient point-and-click interface, most parameter
settings and operations are available through a command line interface
(found in Data/Commands).
===> The following configuration options are available for grace-5.1.25_11:
DOCS=on: Build and/or install documentation
EXAMPLES=on: Build and/or install examples
FFTW=on: Discrete Fourier Transform support
NETCDF=on: NetCDF data format support
PDF=on: PDF output
XMHTML=on: XmHTML based on-line help
===> Use 'make config' to modify these settings
(1) Add new variable, XFREE86_VERSION, to specify which version of XFree86
(3 or 4) to depend to when USE_XLIB is set. XFREE86_VERSION defaults to 3
for now, but adventurous users can override it in /etc/make.conf. When
XFREE86_VERSION=3, USE_XLIB will add a dependency to x11/XFree86; when it
is set to 4, the dependency will be to x11/XFree86-4-libraries. When
XFREE86_VERSION=4, the PKG_IGNORE_DEPENDS and ALWAYS_BUILD_DEPENDS hacks
to avoid messing with XFree86 are turned off.
