Plotting a Function in Gnuplot with Range: 0<z<3, -5<x<5, -5<y<5

[Pessoa]

I want to plot in gnuplot the function , with the range being:

0<z<3
-5<x<5
-5<y<5

What is the command?

Thanks in advance, fellows.

I think it is the set range command. I'm not sure of the syntax, but it's something like set xrange [-5:5]. You might want to check that in the help file.

set xrange[-5:5]
set yrange[-5:5]
set zrange[0:3]
splot -x*x/8.0 - y*y/8.0 + 2
