Tenho melhorado meu código graças a vocês, mas isso ainda parece melhorável, pois parece um copiar/colar feio:
\newcommand*{\LegendFlecheInf}[5]{
\coordinate (C2) at (axis cs:#2, { \FInfAUn(#1,#2) }) ;
\draw node[anchor=#3] (#4) at #5 {$z =#1$};
\draw[fleche] (C2) -- (#4.west) ;
}
\newcommand*{\LegendFlecheEga}[5]{
\coordinate (C2) at (axis cs:#2, { \FEgaAUn(#2) }) ;
\draw node[anchor=#3] (#4) at #5 {$z =#1$};
\draw[fleche] (C2) -- (#4.west) ;
}
\newcommand*{\LegendFlecheSup}[5]{
\coordinate (C2) at (axis cs:#2, { \FSupAUn(#1,#2) }) ;
\draw node[anchor=#3] (#4) at #5 {$z =#1$};
\draw[fleche] (C2) -- (#4.west) ;
}
As únicas diferenças entre os 3 comandos definidos aqui estão em qual função será chamada para calcular a coordenada y da extremidade da seta.
Já removi muita coisa para o MWE mas ainda é grande:

Você poderia substituir
\newcommand*{\LegendFlecheInf}[5]{
\coordinate (C2) at (axis cs:#2, { \FInfAUn(#1,#2) }) ;
\draw node[anchor=#3] (#4) at #5 {$z =#1$};
\draw[fleche] (C2) -- (#4.west) ;
}
\newcommand*{\LegendFlecheEga}[5]{
\coordinate (C2) at (axis cs:#2, { \FEgaAUn(#2) }) ;
\draw node[anchor=#3] (#4) at #5 {$z =#1$};
\draw[fleche] (C2) -- (#4.west) ;
}
\newcommand*{\LegendFlecheSup}[5]{
\coordinate (C2) at (axis cs:#2, { \FSupAUn(#1,#2) }) ;
\draw node[anchor=#3] (#4) at #5 {$z =#1$};
\draw[fleche] (C2) -- (#4.west) ;
}
por
\newcommand*{\Legendx}[6]{
\coordinate (C2) at (axis cs:#2, { #6(#1,#2) }) ;
\draw node[anchor=#3] (#4) at #5 {$z =#1$};
\draw[fleche] (C2) -- (#4.west) ;
}
e depois substitua por exemplo
\LegendFlecheEga{1}{0.6}{south}{C5}{(C4.north)}
por
\Legendx{1}{0.6}{south}{C5}{(C4.north)}\FEgaAUn

Com o ifthen
pacote você pode substituir os três comandos por um novo comando:
\newcommand{\LegendComplex}[6]{
\ifthenelse{\equal{#6}{inf}}{\coordinate (C2) at (axis cs:#2, {\FInfAUn(#1,#2)});}{}
\ifthenelse{\equal{#6}{sup}}{\coordinate (C2) at (axis cs:#2, {\FSupAUn(#1,#2)});}{}
\ifthenelse{\equal{#6}{ega}}{\coordinate (C2) at (axis cs:#2, {\FEgaAUn(#2)});}{}
\draw node[anchor=#3] (#4) at #5 {$z =#1$};
\draw[fleche] (C2) -- (#4.west) ;
}
Você deve fornecer um novo parâmetro (sup, inf ou ega) especificando qual função você deseja chamar.
