Grace project is an open source WYSIWYG 2D plotting utility for M*tif and the X Window System.

Grace is cross-platform and it runs on practically any version of UNIX-like OS.

Features:

• General:
• WYSIWYG design
• Convenient point-and-click graphical user interface
• Precise control of graph features
• True publication quality
• Graphs refresh almost instantly
• Export Options:
• Exports high-resolution graphics to (E)PS, PDF, MIF, and SVG formats
• Supports cross-platform PNM, JPEG and PNG formats
• Device-independent Type1 font rastering, including anti-aliasing, ligatures and kerning
• Graphing Flexibility:
• Unlimited number of graphs
• Unlimited number of curves on a graph
• Up to 256 customizable colors
• 9 dashed line styles
• 32 fill patterns
• 10 built-in marker symbols; plus, any character glyph from any font can be used as a marker
• Color/fill markers
• Text annotations with subscripts, superscripts, mixed fonts, styles and colors and more complex typesetting
• Curve Fitting:
• Linear and nonlinear least-squares
• Calculation and display of residuals
• Arbitrarily complex user-defined fitting functions, including dynamically loadable C/Fortran/... modules
• Fitting with constraints
• Region restrictions
• Fitting with arbitrary weight functions
• Analysis Capability:
• FFT
• Integration and differentiation
• Histograms
• Splines, including Akima splines
• Interpolation and smoothing
• Convolution, correlation, and covariation
• Sorting
• Data Formats:
• Unlimited data size; up to six dimensions plus an optional array of strings
• Reads text data input files
• Reads 1D netCDF files
• Programmability:
• Built-in programming language
• Math functions manipulate entire array
• Variables, including arrays (1D)
• User-definable functions via loadable modules
• All aspects of plot outlook can be programmed
• Controllable by external programs
• Customization/Extensibility:
• Dynamic module loading - write your own C/Fortran/...
• User-defined colors
• User-supplied fonts and encodings

What is new in this release:

• Interface:
• [DC] mention object type when asking for user's confirmation on delete
• Parser:
• [ES] added "LINCONV(set1, set2)" command - an equivalent of Transformations->Linear convolution * [ES] added "VOIGT(gamma, sigma, x)" function (rep. #2144)
• Bug fixes:
• [ES] in the grace_np library GraceClose() could kill all user processes if by that time the Grace subprocess has exited (rep. #2035) * [ES] certain hand-modified settings in project files might cause the GUI crash (incl. rep. #2139) * [ES] ungraceful closing of anonymous pipes could result in high CPU load
