Chage 
  [X,Y,Z]=meshgrid(-7:0.5:7,-7:0.5:7,-7:0.5:0);
to
  [X,Y,Z]=meshgrid(-7:0.1:7,-7:0.1:7,-7:0.1:0);

For interpolation see interp3 function.

I assume you have rotated the plot by mouse - octave doesn't
know about mouse-gnuplot interactions. If you choose view
angles by mouse you can replicate them using octave function
"view()" - then print produces expected image.

In my case gnuplot shows angles in bottom-left corner of
window, like this "view: 60.0000 30.000". Calling
view(60,90-30) in octave you get the same result.
