Androidplot - X-Achsen-Labels abgeschnitten
Ich erstelle ein Balkendiagramm, bin jedoch auf ein Problem gestoßen, bei dem die Beschriftungen auf der x-Achse auf einem Tablet abgeschnitten wurden. Beigefügt ist das richtige Layout auf einem Telefon und das falsche Layout auf einem Tablet.
Weiß jemand, warum dieses Problem auf einem Tablet auftritt und wie es behoben werden kann?

Dies ist mein Code zum Erstellen des Balkendiagramms.
