x[1] = is X for atom 1
.
.
x[i] = is X for atom i
y[i] = is Y for atom i
z[i] = is Z for atom i

d[1][2] is the distance for atoms 1 to 2
d[i][j] is the distance for atoms i to j


///-----EXAMPLE-----
x[1]
z[3]
d[1][2]-y[3]
///-----------------
this plot 3 columns,
the firt is de X of the atom 1
the second is the Z of atoms 3
and the last is the diference betwen de distance of
atom 1 to 2 minus de Y of the atom 3
