Try
Exnxn: express(express(E~n)~n);

I also had to fix this in order to reproduce Bart's example.
Bart:
I have checked your example under Gnuplot 4.4.0 and you are right: the z
intervals don't seem to be of equal length compared to the x and y
intervals.
This is a bug in 4.4.0, which was fixed in 4.4 patchlevel 2.
