Hmm, what you show are at least two data structures:

This is the first

Now what is what? x, y, z? Where does the colour info come from?
And I'm sure you've checked gnuplot's demo gallery
http://gnuplot.sourceforge.net/demo_5.4/ on 3D plots and surfaces.
What is your plot supposed to look like? What can you make from the
scripts shown there, what doesn't work for you?
Best,
Karl
