QtiPlot a data analysis and scientific plotting software Scientists often need to use data analysis and plotting software. The purpose of this software is to develop an open source platform independent alternative to proprietary scientific software like Origin, SigmaPlot, Regressi or Igor Pro. QtiPlot can be successfully used for teaching as well as for complex data analysis and visualisation and is being used in companies, high schools, universities and reseach institutes all over the world. QtiPlot is a program for two- and three-dimensional graphical presentation of data sets and for data analysis. The plots can be produced from data sets stored in tables or from analytical functions. Some features are;

QtiPlot is fully scriptable via Python, which gives you the possibility to use powerfull existing scientific tools, such as SciPy, thus bringing unlimited data analysis power;
OpenGL based 3D plotting: height maps, user defined functions and parametric surfaces;
Publication quality 2D plots: Error Bars, Multilayer Plots, Bar Plots, Pie Plots, Vector Plots, Contour and Image Plots;
Easy export of plots to vector formats (EPS, PS, PDF, SVG) and to various raster image formats (BMP, JPG, PNG, TIFF etc ...);
Easy ASCII-Import/Export of single or multiple files;
Built-in data analysis routines: statistics, sorting, FFT, data smoothing (Savitzky-Golay, FFT smoothing, and moving window average), data filtering (low/high/band pass and band block filters), convolution/deconvolution, correlation, interpolation, numerical integration/differentiation, matrices optimized for image analysis etc...
