Ich habe folgende Grafik:
Welches wird aus der Lösung entnommenHier. Ich möchte der Grafik noch etwas Text hinzufügen, sodass sie etwa so aussieht:
Um die hohe Verzerrung, die niedrige Verzerrung und die Kombination aus beiden anzuzeigen - zusammen mit den Bezeichnungen "Überanpassung", "Unteranpassung" und "Gute Balance". Wie kann ich diesen Text in die aktuelletikzpicture

Sie können Kommentare oder Text mit \node[<options>](<name>) at (<coordinate>){<text>};innerhalb von hinzufügen scope. Darüber hinaus ermöglicht die TikZBibliothek positioningdie Lokalisierung von Knoten in Bezug auf andere Knoten mitoben/unten,rechts/links<shifting part>und deren Kombinationen. Darauf können die optionalen Argumente und folgen <of part>.
Zum Beispiel im Inneren scope:
\node[red] (lowlow) at (2.2,2.5) {Low bias, low variance}; % <-- here
oder
\node[red, below= -2.75cm of over] (lowlow) {Low bias, low variance}; % <-- here
und dann draußen:
\node[green,below = 3cm of lowlow] {Good balance}; % <-- here
