This function returns a data.frame with the following variables:
cat_x,cat_y: coordinates of the cations in the ternary diagram (scaled between 0 and 1).
an_x,an_y: coordiantes of the anions in the ternary diagram (scaled between 0 and 1).
d_x,d_y: coordinates of the samples in the central diamond (scaled between 0 and 1).
