Thank you. It worked. You probably meant "splot" rather than "plot"
below, and with that changed everything was fine. However, I have a
few questions that I was not able to figure out:

I am getting a smooth surface without a grid. How can I get grid lines
as well (like in the plots I attached)? Also, is it possible to
interpolate these grid lines (i.e. as you say minimize or maximize
their number)? I looked at "isosamples", but it works only for
functions and not for data files.
Finally, can "pallette" be used "with lines", i.e. get the palette
colors for the different surfaces if these surfaces are just
represented as a grid (like in the plots I linked to)? I do not want
to get so different colors for the different surfaces, but rather a
smooth change from one color to another, for example from white to
blue when you go from the first surface to the last one. I was not
able to make this work if I use the option "with lines".
Thanks.
