gracegtk

GraceGTK is an evolution of the grapher Grace (grace-5.1.22).
It is an integrated tool to analyse numerical data (linear and non linear fit, Fourier or wavelets transform,...) and visualize the results as curves, bar charts or 2D color maps, up to a drawing suitable for publication in a scientific journal.

GraceGTK is based on the GTK API with higher interactivity and new features such as a tree view of the drawing.

The home site for Grace is http://plasma-gate.weizmann.ac.il/Grace
The first release of GraceGTK had been done through this site and you can track the earlier history of the project in the Development forum on this site.

Another fork of Grace is QtGrace by andwin. It is based on Nokia Qt API and can be found at http://qtgrace.sourceforge.net/
