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.

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

What's New in 0.8.8 Stable Release:
Improved the 3D plotting capabilities by adding the possibility to use color map files, the choice between orthogonal and perspective modes and the possibility to animate the 3D plots.
Added the possibility to attach the grid and the 2D plot curves to different axes. The oposite axes may now display different scales.
Upgraded to Qwt5.0.0-rc0, which fixes misalignment between in and out ticks in 2D plots.
Fixed saving/restoring of 2D plot markers to/from project files.
Fixed bugs when drawing Spline curves.
Added a VerticalSteps plot style.
Added an Origin-like feature: when plotting a list of columns, if some columns are declared as having yErr or xErr type, they are plotted as error bars.
Dropped support for project files with version lower than 0.6.4: in order to open project files older than this version please use QtiPlot-0.8.7
Fixed bug in NonLinearFit class: setting only one parameter caused crashes.
Improved the TableStatistics behavior: they now react to columns being deleted or renamed in the base table and the user can use them directly for plotting.

What's New in 0.8.9 RC2 Development Release:
A lot of bugfixes and improvements.
