2つの異なるデータフレームを使用して、積み上げ面積プロットにラインプロットを課します

以下のスタック領域プロットを生成するコードを準備しました。

このプロットは、指定された領域の平均状態を種ごとに分類して表しており、1つのデータフレームに含まれています（サンプルデータを参照）。ただし、種の内訳がない最小値と最大値を含む2番目のデータフレームがあります。この追加情報を、2つの線プロットを介して既存の積み上げ面積プロットに適用したいと思います。上記の望ましい結果の大まかなマークアップを参照してください。

2番目のデータフレームを最初のデータフレームに結合しようとしましたが、それでは目的の結果に近づくことができないようです。

最終的な凡例の目的ですべてをaes内に配置するのが理想的ですが、この時点で、最小線と最大線を単純にプロットすることにします。現在、積み重ねられたエリアの種のプロットは、機能的な凡例を生成します。

サンプルデータと既存のコードは次のとおりです。
