Use the contour function.

If they are not already gridded (in a regularly-spaced 2D array), use the griddata (or related functions) to interpolate them into a grid so contour can plot them.

i try to use that function contour, but it said Z coordinate should be 2D array, but I can't make it.

and there is no correleation between Z datas. cause it is just thickness..

Use the griddata function that I linked to.

I have no idea what you want to use in the file you posted.
