How to make a {x,y,z} plot of a data set

I’m a beginner using Mathematica so I really need help with this.

I have a data set which consist in a [X,Y] vector and a matrix of Z values. For every step of Y, I have a vector X, which is always the same, and a set of Z values (every row of the "Z" matrix is a set for each step). So, I have, for example: {X[1…vector lenght],Y[1],Z[MatrixRow 1]} as my first set of values. I need to put them all in the same 3D plot, but I’m not sure about how to do it.

Thank you and sorry for my english :c
