KMatplot

A new Qt-only GUI, which requires Qt 3.0.1, was
written. A new graph wizard was added.

Many bugs have been fixed. There is a new numeric Python module, a double buffering display mode, and examples. Some autoconf scripts have been updated.

This release adds cut/copy/paste, undo/redo, a formula parser (still under development), a colored area under the surface, v-gradient, plotting of 4d data (still under development), custom tics values, fast selecting of graph elements by middle button click, and grouping/ungrouping of objects. It allows many pages in a single document. Axes can be freely added to / removed from a graph. Surfaces and contours can display non-gridded data (using Delunay triangulation). The general data storing policy has changed; vectors are stored as columns. There are many bugfixes.

Surfaces now use a row index vector. This release
has the ability to autorun from within Octave and
Scilab, loads/saves arrow styles, no longer
crashes when loading/saving or deleting objects,
and has updated Scilab functions, global data
sheets, rulers in the page view, and scatter and
trajectory 3D plots. Exporting(requires) to Qt
Metafile, PNG, JPEG, BMP, pdf(GhostScript),
eps(Ghostscript), xfig(pstoedit) and other formats
provided by GhostScript, pstoedit, or ImageMagick
has been added.

Major redesign - full page view, contour plots, and many other small changes.
