Re: [Axiom-developer] problem plotting simple functions

[Ralf Hemmecke]

Oh, interesting,

                        AXIOM Computer Algebra System
                       Version: Axiom (September 2006)
              Timestamp: Friday September 29, 2006 at 14:21:21

I think I compiled Gold from the tla archive.

On all 4 cases I get a window with title AXIOM2D or sin x*y, but I don't 
see any plot. Maybe I should compile a newer version. (Don't care about 
my case, I switched from debian sarge to etch without recompiling Axiom. 
So maybe that is a reason.)
