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.
