QtiPlot - is a graphing and analysis software for scientists and engineers.
According to the author of QtiPlot his purpose was to develop a free, platform independent clone of Origin. The result is still far away from it's model, but there's a "wish to" list which he is constantly working on. The program uses the GNU Scientific Library 1.6, for 2D-graphing Qwt 0.2.4, and for 3D-visualization Qwt3D 0.2.5 - these libraries will be installed by this installer (further information is available from the ReadMe inside the installation folder).

Here are some key features of "QtiPlot":
2D and 3D data plotting
ASCII-Import
powerful and versatile spreadsheets and calculations in column-logic
non-linear y=f(x) curve fitting and estimation of statistical errors of the fit-parameters.

What's New:
separate installer packages for Macs with PowerPC or Intel processor(s)
python scripting support (REQUIRES existing python 2.4 on the target computer)
Added support for evaluating mathematical expressions and executing scripts using the Python interpreter on Linux and Mac OS X. Scripts can be edited and executed via Note windows or using a script window (which can be launched via a handy shortcut: F3). As soon as the port to Qt4 is ready, these features will be also available on Windows.
Completely rewritten all fit routines in order to make them available to the scripting interface. Now fit routines support weighting and their output is highly customizable: the user may choose to define the resulting fit curves as mathematical expressions (normal functions) or via a data set.
Improved the Non-linear Fit dialog.
Improved the Help Browser. A much improved version of the manual is now available online (thanks to Roger Gadiou).
Fixed bugs causing crashes during Multi-Peak Fits and other analysis operations.
Improved saving and restoring of user global settings, including saving of ASCII import options.
Fixed crash occuring when deleting multiple table rows.
Improved behaviour of column/row headers in tables/matrices.
Added new symbols to 2D plot curves.
Added an Origin-like title bar menu for the MDI windows.

Requirements:
Mac OS X 10.3 or later
an installation of Trolltech's Qt/Mac 3.3 C++ framework (a download bookmark for an installer package of Qt/Mac 3.3.4 GPL-Edition is provided with the installer).
