以下の例では、波のプロファイルと船のプロファイルの間の陰影が付いた画像 (成功) と、喫水線と\zeta=0歪んだ水中の船体プロファイルの間の陰影が付いた画像 (失敗) の 2 つの画像を提示しようとしています。...同じ構文を使用しfill between、多くの投稿を精査しましたが、エラーが見つからないようです...誰かに明らかなのでしょうか?

更新された回答
報告されたバグは修正され、PGFPlots v1.16 のリリースにより、あなたの例では期待どおりの結果が直接得られます。
元の回答
これはすでに報告されているバグPGFPlots でfill betweenを と一緒に使用するとsoft clip、軸の境界に達します。したがって、解決方法は簡単です。ymin値を など、より低い値に設定する-0.76と、目的の結果が得られます。
ここでは、コードの関連部分の結果のみを示します (さらに、この奇妙な動作がどこから来ているのかを証明するための追加情報も示します)。
