If I put your data into the file "data.dat" for me it works the following:

set title 'pm3d at s (surface) / ticslevel 0'
set xlabel 'x'
set ylabel 'y'
set zlabel 'z'
set xrange [0:4.5]
set yrange [0:4.5]
set zrange [-1000:0]
set cblabel 'colour gradient'
set pm3d implicit at s
splot 'data.dat'

Have a look to the minimal script at 
<http://gnuplot.sourceforge.net/demo_4.6/pm3d.2.gnu>
