Qtiplot

Data analysis and scientific plotting

The purpose of this project is to develop a free open source, platform independent alternative to Origin. QtiPlot is being actively improved, all your suggestions to our “wish to” list and all your contributions are most welcome!

Features

• QtiPlot is fully scriptable via Python, which gives you the possibility to use powerfull existing scientific tools, such as SciPy
• OpenGL based 3D Plotting
• Publication quality 2D plots
• Easy export of plots to vector formats EPS, PS, PDF and to other various image formats BMP, JPG, PNG, TIFF etc …
• Powerful and versatile spreadsheets and calculations in column-logic
• Easy ASCII-Import/Export of single or multiple files
• Linear and non-linear y=fx curve fitting and estimation of statistical errors of the fit-parameters
• Multi-peak fitting with Gaussian and Lorentzian peak profiles
• Data analysis 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, etc…
• Matrices optimized for 3D plotting
• Templates support all the settings for plots 2D/3D, tables and matrixes can be saved to ASCII files and restored later on for a fast editing process
• Project files based on folders, a powerful project explorer with extensive built-in features drag and drop, searching facilities, etc…
