Der folgende Code liefert mir die gewünschte Anzeige. (Ich weiß, dass der Code mit foreachBefehlen viel effizienter hätte sein können.) Ich hätte gerne einen konsistenteren Code für die Legende. Hat jemand Vorschläge?

prüfen Sie, ob Ihnen die folgende Lösung beim Zeichnen Ihres Diagramms helfen kann:
\documentclass[margin=3mm]{standalone}
\usepackage{pgfplots}
\pgfplotsset{compat=1.16}
\begin{document}
\begin{tikzpicture}
\pgfplotstableread{% here should be real coffee price

Notiz:
- Durch die Verwendung des Pakets
pgfplotswird der Code für Ihr Bild erheblich reduziert, vereinfacht und weitaus übersichtlicher - für Kaffeepreise verwende ich die angegebenen Koordinaten in Ihrermwe(minimales Arbeitsbeispiel), es besteht jedoch der Verdacht, dass die tatsächlichen Preise etwa vierzigmal höher sind. Sie müssen daher die Daten in der Tabelle überprüfen
\mydataund dann entsprechend korrigieren. - Wenn Sie ein größeres oder kleineres Diagramm haben möchten, ändern Sie einfach die Option
widthvon 80 mm auf die gewünschte Breite - als Dokumentklasse wähle ich aus
standalone, was beim Zeichnen von Bildern praktisch ist. Sie können es jedoch durch ersetzen{amsart}. - für die Positionierung des Bildes auf der Seite verwenden Sie nicht aproach wie Sie in Ihrem zeigenmwe. besser ist es, es in einer Float-Umgebung einzuschließen
\begin{center} ... tikzpicture ... \end{center}oder noch besserfigure
