[D3js] Méthode remove() ne marche pas

Bonjour,

Je suis en train de faire des graphiques, mais la fonction remove() de d3 ne fonctionne pas. Je sélectionne une date et j'affiche le graphique correspondant. Si bien que mes graphiques se superposent à l'infini. Est-ce que vous pourriez m'aider ? Merci !
