Combine the power of sophisticated data analysis with the ease-of-use of a spreadsheet.
DADiSP (pronounced day-disp) is an interactive graphics worksheet -- a visually oriented software package for the display, management, analysis and presentation of scientific and technical data. If you collect, manipulate, edit, reduce, transform, display or analyze data, DADiSP can handle and simplify your data needs. In short, if you work with technical data, DADiSP is for you. A DADiSP worksheet is comprised of as many analysis windows as you need. The data and graphs in each DADiSP window can be related through formulas, permitting you to define your own analysis chain without the need to master an arcane programming language. Like a business spreadsheet, when new data is loaded into the raw data windows, dependent windows automatically recalculate and update.
Easy to use data analysis and graphing app that avoids the necessity of complex programming. Fast performance, small footprint, handles large data well. A good tool to have for many scientific/engineering applications and a better alternative for those who feel handicapped by Excel.
Cons
No native Linux version, requires Wine or similar Windows emulator.
Summary
Excellent data analysis and visualization tool. The spreadsheet concept greatly simplifies the implementation of analysis without tedious coding. Includes many functions and also provides a C/C++ based scripting language. For me, easier to use than other technical computing alternatives. Great for exploratory data analysis. After just a few days, DADiSP has become my "go-to" number crunching application.
