Assigns data for Saccani's diagram into Figaro template (list 'sheet') and                                   
appropriate values into 'x.data' and 'y.data', the latter also into 
the matrix 'results'.

The diagram of Saccani (2015), based on NMORB-normalized Nb[N]-Th[N] values (Sun and McDonough 1989), serves for discrimination of geotectonic setting of basalts. The individual fields are illustrated on the original figures of Saccani's work:
