QtiPlot is a data analysis and scientific plotting. Free clone of Origin.
QtiPlot uses Qt and the excellent libraries Qwt, GSL, QwtPlot3D and Ingo Berg's Fast Mathematical Parser.
Features:
- Neat 2D and 3D data plotting
- ASCII-Import
- Spreadsheet and calculations in column-logic
- Great non-linear y=f(x) curve fitting and estimation of statistical errors of the fit-parameters
What is new in this release:
- Improvements:
- Improved support for the Dock menu on Mac OS X.
- Improved restoring of statistic tables.
- Improved handling of error messages in Savitzky-Golay smoothing filter.
- Improved plotting of 2D plot layers with shared axes.
- Improved error bar handling when plotting a table column selection.
- Implemented feature request #5451: "Do not expand tree in Project Explorer".
- Implemented feature request #5458: "Fit wizard remove only fits from session".
- Updated translations: Italian (thanks to Renato Rivoira), German (thanks to Daniel Schury) and Romanian.
- Updated Italian manual thanks to Renato Rivoira.
- Bug fixes:
- Fixed crash when opening old projects containing spectrograms.
- Fixed duplication of 2D plots with respect to the synchronization of scales.
