- Abscissa 2.1
- a 2D Plot and Fit Program
-
- Abscissa is a 2D Plot and Fit program which
- is designed for scientific daily work.
-
-
- It offers:
-
- - ASCII import and export
- - EPS export
- - fast reading and plotting
- - plotting in many styles
- - linear and logarithmic axes
- - text and graphic
- - x,y error bars
- - 4 interpolation methods
- - user entered functions f(x)
- - flexible functions (parameters, user data)
- - numerical derivation, integration
- - data manipulation with functions
- - parameter fitting with a Least Square Method
- - fit of function with several independent coordinates (Rn->R)
- - API: an interface to control Abscissa by external programs
-
- New in Version 2.1
- - floating (axis coordinates placed) text objects
- - undo for data altering actions
- - some new API functions
- - some new formula features
-
- New in Version 2.0
