Palmira,


(%i1) plot2d (sin(x), [x, 0, 2*%pi],[gnuplot_term,  dumb ]);

works as expected in my linux box.

To get an eps file:

(%i2) plot2d(sin(x), [x, 0, 2*%pi],
             [gnuplot_preamble,
              "set terminal postscript eps;set out 'myplot.eps'"])$


In png format:

(%i3) plot2d(sin(x), [x, 0, 2*%pi],
             [gnuplot_preamble,
              "set terminal png;set out 'myplot.png'"])$


There are lots of programs to make file conversions; for example, when I
want 'myplot' in pdf format I write in command line:

$ epstopdf myplot.eps

With Gimp, you can convert png to jpg and other bitmat formats.

Hope this helps
