[Gnuplot-info] 3d grid

[Umut E. <j.s...@o2...>]

Hei *,

Is there anyway to have a real 3 dimensional grid?
I use this commands,
gnuplot> set grid xtics ytics ztics
gnuplot> set ztics 0.5
gnuplot> set pm3d
gnuplot> splot sin(x)*cos(y)

which draws a grid in a plane(2d) xy,xz and also
yz. It looks like it draws grid around boxes 

I want to have it in xyz -would look like small cubes
cutting the whole function surface. 
Any Hints? 

Thanx,
Umut
