Abscissa

Abscissa is a program to make high-quality 2D-plots from data given in ascii table form. Data can be created and modified by means of a user defined formula. A least-square-fit routine helps to optimize the parameters of this formula in order to fit the given data best. It is made for scientists.

Main Features:

  • ASCII data import and export
  • fast reading and plotting
  • plotting in many styles
  • linear, logarithmic, and date axes
  • text objects in the diagram
  • x,y error bars
  • 4 interpolation methods
  • user entered functions f(x)
  • flexible functions (parameters, user data, compiled C-code)
  • parameter fitting using a Least-Squares Method
  • fit of function with several independent coordinates (R^n->R)
  • external programs can use Abscissa as plot front-end
  • perl scripts can be recorded, played, and saved
  • data editing in a spread sheet
  • data sorting
  • data statistics and correlation
