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
