Androidplot - Etiquettes de l'axe X coupées

Question

Je crée un graphique à barres, mais j'ai rencontré un problème avec les étiquettes d'axe x étant coupées sur une tablette. Ci-joint la disposition correcte sur un téléphone et la disposition incorrecte sur une tablette.

Est-ce que quelqu'un sait pourquoi ce problème se produit sur une tablette et comment y remédier?

Ceci est mon code pour créer le graphique à barres.

Le problème semble être l'espace est insuffisant dans les widgets graphiques de marge inférieure. Si vous ajoutez ceci au code XML de votre parcelle:

androidPlot.graphWidget.marginBottom="100dp" 

Ensuite, le problème devrait disparaître. 100dp est probablement overkill donc vous aurez besoin de le composer dedans mais vous obtenez l'idée :)
