README for:
Abscissa 1.5
a 2D Plot and Fit Program
Abscissa is a scientific 2D plot program.
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
- color support
- 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
- multi dimension fitting
new in 1.4 compared to 1.1 :
- layout-files to save most attributes of a plot
- unlimited number of curves
- unlimited numbers of windows
- modify x-values of curves
- simultaneous change of attributes of many curve
- parameters can be fixed for fitting
- Markers to recall parameters (designed for spectroscopy)
- search all local maxima/minima of a curve
- matrixes can be fitted to suffice given eigenvalues
- run only under NS 3.x
New in Version 1.5
- bug fixes:
all text-objects in layout-files
window ordering
- a second x- and y-axis with independent range is available.
- binary format input/output
- improvements in markers
- run on MC680xx and Intel
