gnuplot questions



Hello *,

I have gnuplot-4.0 installed on my Gentoo Linux box, and a recent cvs 
maxima. When I run gnuplot interactively, I can rotate and rescale 3d 
plots by the mouse. When the plot is produced by maxima, I can't.
[gnuplot_preamble,"set mouse"] does not help. How can I make 
maxima-produced plots "live"?

How can I ask gnuplot to eliminate hidden lines? I could not find such an 
option.

Besr wishes,
Andrey
