Heightmaps -- generate from x,y,z, coords...

i have a file that has data of just depth, for example, here is what my stored data is like in my dataArray:

100 80 40 400 200 220 300

these numbers represent depths and that is it, so that means on my x, y, z coords the y is the only thing changing. i am wanting to know how i turn this “points” if you will into a 3-D heightmap to give a clear view of the depth. afterwards i am going to put a texture over it, but thats for another time. i just need to be able to get this into a heighmap. any recent links or code anyone would be willing to share? thanks!
