QtiPlot v0.9.1 released
Version 0.9.1 of QtiPlot, an Origin-like scientific plotting and data analysis program, has been released. Major changes:
- The behaviour of matrices is now completely Origin like: dual image/data view mode, support for flipping and rotating images, 2D histograms and the possibility to save matrices as bitmap or vector image files. Fast Fourier Transformations for matrices was also implemented. This is a restricted module (the code is not GPL) and is available only to users having subscribed for a QtiPlot binaries maintenance contract.
- The fit wizard was higly improved: all the fit models and the initial guesses for the fit parameters can be saved to XML files, added the possibility to restrict the search range for the fit parameters and added a preview functionality for the fit models, allowing to determine efficiently the initial fit values.
- Added support for 3D parametric surfaces.
- Added a preview option to the import ASCII dialog and the possibility to import new data as read-only columns.
- Improved the handling of tool bars and added a new tool bar for table column operations.
- The import of Origin 7.5 project files was improved thanks to Alex Kargovsky.
- Fixed export to vector formats on Mac OS X.
