core-plot x軸ラベルは表示されません。

Question

縦棒グラフサンプルを使用して、y値が0..1、x値が1..nのグラフを作成しましたが、データソースのCPTBarPlotFieldBarLocationセルに指定されたxラベルインデックスは表示されません。私はy軸のラベルを使用しません。

私はそれらをクリッピングしていると思われます。古いIBのように、さまざまなグラフ領域の境界線を描く方法はありますか？

x軸プロットラベルは、例のように数値でない文字列です。私は何を壊しましたか？目に見える手がかりがあった場合はここに私のセットアップ

ステートメントx.labelFormatter = nil;は、自動軸ラベルを削除します。ラベルフォーマッタとラベルのテキストスタイルを指定すると、軸はラベル付けポリシーに基づいて自動的にティックとラベルを作成します。
