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.
Features:
- 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.
