Its interface is similar to that of gnuplot, but its graphics engine is optimised to produce output in a style appropriate for inclusion in academic journals.
The LaTeX typesetting system is used to render all text labels, making it easy to annotate graphs with mathematical expressions.
In addition, Pyxplot has many more flow control constructs than gnuplot, making it much easier to perform batch operations.
All of Pyxplot's numerical analysis commands, such as curve-fitting, Fourier transforms and histogram generation also natively support quantities with physical units.
Pyxplot's vector graphics drawing commands allow positions on the page and rotation angles to be specified by quantities with appropriate physical units.
