Hi, I have a set of data in the table format

{{1,2,3,4},{10,2,5,6,5},{20,1,3,4,7},{30,3,1,6,9}}

where the first line is the x axis, but the y column is the first number of the following lines

TableForm[{{1, 2, 3, 4}, {10, 2, 5, 6, 5}, {20, 1, 3, 4, 7}, {30, 3, 1, 6, 9}}]

So x={1,2,3,4}, y={10,20,30} and f(x,y) are the remaining data.

How can I plot these data in a 3D like form?

Thanks

Simone
