Ctioga 1.0 has been released. It is the first really functionnal release. Ctioga makes great use of the Tioga plotting library to plot graphs with a simple command-line syntax. Something as simple as

ctioga data.dat

is enough to make a nice PDF file with the second column of the file plotted against the first.

ctioga data.dat@sin($1):cos($2) />
plots the cosine of the second column as a function of the sine of the first... And so so

Ctioga is extremely customizable, comes with many options to control the style, the parsing of the files, the PDF file produced and many more. It also comes with ctable, a small program particularly useful for analyzing scientific data.
