File extension abs information

One of the associated applications to file extension ABS is abscissa, which is a program that makes high quality two-dimensional plots from given data in the form of ASCII table. Data can be modified and created using means of user-defined formulas. Given data is best fitted through parameter optimization that is helped in part by a routine that is least square fit. Scientific looking plots are what this application is built to make, though settings are available that make them look like they were made using Windows Excel.
The features of Abscissa with a file extension ABS are ASCII data export and import, fast plotting and reading, many styles of plotting, date logarithmic and linear axes, diagram containing text objects, error bars of x,y and four interpolation methods. Other features include user entered f(x) functions, flexible functions such as compiled C-code, user data and parameters, parameter fitting utilizing a Least-Squares Method, and several independent coordinates with fit for function (R^n>R). The settings are labeled as layout and are kept in a separate file, with an extension marked as .abs.
