Zeichnen Sie mit Tikz sechs Diagramme in einem Beamer

Question

Ich versuche, einen Beamer mit 6 Diagrammen einzurichten, die in einer 2x3-Matrix angeordnet sind. Wenn ich jedoch versuche, die Größe der Diagramme zu ändern, damit sie in den Rahmen passen, bewegen sich die Bilder nicht oder sie fangen an, seltsame Dinge zu tun. Ich habe versucht, andere Umgebungen wie minipageoder zu verwenden columns, und habe auch Befehle wie \scaleboxoder \resizeboxmit wenig Erfolg ausprobiert.

Unten hinterlasse ich ein MWE und das Ergebnis meines Codes. Für jede Hilfe, die 6 Grafiken in einen Beamer einzupassen, wäre ich sehr dankbar.
