All releases tagged Major bugfixes

Changes: More weightings and residuals for regression and nonlinear fit were added. Wavelet and hankel transformation were added, and analysis functions were improved. Additionally improved was not only the surface and qwt 3D plot but also the behavior with nonlinear scales and the support for LaTeX labels. LabPlot now can import/export data from/to PostgreSQL, MySQL, and other sources via the KexiDB and Origin opj projects (Origin worksheets only). The scripting support was completely rewritten and many bugfixes were made.

Changes: The internal plot structure was completely redesigned and improved. The parser now supports functions with more parameters. A contour plot was added to the surface plot. It is now possible to save worksheets as TIFF and JPEG 2000. A user guide was written (as a KDE handbook) and some bugs were fixed.
