SciDAVis is a free interactive application aimed at data analysis and publication-quality plotting. It combines a shallow learning curve and an intuitive, easy-to-use graphical user interface with powerful features such as scriptability and extensibility. SciDAVis runs on GNU/Linux, Windows and MacOS X; possibly also on other platforms like *BSD, although this is untested.
SciDAVis is similar in its field of application to proprietary Windows applications like Origin and SigmaPlot as well as free applications like QtiPlot, Labplot and Gnuplot.
- Tables (2D data), matrices (3D data), graphs (2D or 3D plots) and notes (text notes or Scripts) are gathered in a Project and can be organized using folders. - Data for tables or matrices can be entered directly or imported from ASCII files. - Cell values in tables can be computed using standard and special functions (and much more if you have Python installed). Each table cell can be assigned an individual formula. - Multi-level undo/redo for tables and matrices. - Many built-in analysis operations like column/row statistics, (de)convolution, FFT and FFT-based filters. - Extensive support for fitting linear and nonlinear functions to the data, including multi-peak fitting. - Publication-quality 2D plots of various types including symbols/lines, bars and pie charts which can be exported to a variety of formats (JPG, PNG, EPS, PDF, SVG and more). - Interactive 3D plots with export to a variety of formats, including EPS and PDF. - Note windows with support for in-place evaluation of mathematical expressions. With Python installed, you can even access other objects in the project, e.g. for rapidly writing an import filter for a custom data format.
