postscript output



Hi!

I have got some problems to print plots produced by Maxima.
I think the simpliest solution should be to produce a postscript
file, which - according to the docs - can be done this way:
	(C4) plot2d(x^2,[x,-5,5],[PLOT_FORMAT,PS]);

I receive a   FALSE	from maxima and find a file called
maxout.ps in my home directory.

maxout.ps contains a long list of pairs of numbers - nothing else.
How can I make this a printable .ps file?
Or do I have to set anything else?

Thanks for your answers.

Uli.

P.S. Openmath and Geomview don't seem to work properly on my
     system (FreeBSD -CURRENT) - to hack these wouldn't be the
     simpliest solution. The gnuplot option works, but as far as
     I know, gnuplot only produces boxplots.
