moving a graph in another slide to fit in one page

Question

I need to move the graph in the third page slide in the second page and make everything fit.

%\setbeamercolor{titlelike}{parent=structure,fg=blue} %colore titoli
%\setbeamercolor{titlelike}{parent=structure,fg=yellow,bg=cyan} %colore e background in un comando
