No, I am not aware of such a package. But Mathematica and/or Matlab
should be able to do it (well, is there something thay cannot do?). As a
first try, why not producing 512 "OnLine" plot (each with 512 points),
and smooth the lines with Gnuplot? (between two adjacent lines, it
should't that bad...).
