Molto carino questo effetto, peccato proprio non usare Beamer. (:evil: però almeno con PowerPoint ho fatto in fretta)
Purtroppo mettendo l’ambiente [tt]groupplots[/tt] si ottiene un guaio:

In pratica, invece di fare un grafico SOMA, un grafico NUCLEO e un grafico NUCLEOLO, ne crea 3 usando in sequenza le coordinate (completamente sbagliato perchè invece dovrebbe riunire tutte le coordinate [tt]1, XXX[/tt] per il grafico che ha [tt]xtick=1[/tt] e [tt]xticklabel=SOMA[/tt], e così via) e riferisce tutte le barre ai controlli.
Ma con l’ambiente standard [tt]axis[/tt] non succede così 😕
