XL-Plot allows you to quickly create graphs for scientific publication.

It reads ASCII files and it outputs a vector drawing.

XL-Plot contains a few basic statistical functions such as the Student t-test and linear correlation of two sets of data (two columns in a spreadsheet). The program has also a number of built-in functions which can be fitted to column data in a spreadsheet or to a curve in a graph, and you can easily add your own fitting functions.

XL-Plot also includes the Fourier Transformation and Matrix inversion function which can be useful in solving a set of linear equations simultaneously.
