Ich bin mir ähnlicher Fragen bewusst, aber da sie nicht genau dieselbe Syntax verwenden wie die, die ich versuche, kann ich nicht erkennen, was der Unterschied zwischen meiner Art, Funktionen aufzuschreiben, und den anderen ist. Folgendes versuche ich zu tun:
\documentclass[13pt,a4paper,headlines=6,headinclude=true]{scrartcl}
\usepackage{amsmath,amssymb,stmaryrd}
\usepackage{tikz,pgfplots}
\usetikzlibrary{datavisualization.formats.functions}
%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%
\begin{document}
%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%
\begin{tikzpicture}[yscale=.5, xscale=.5, scale=3.5]
\datavisualization
[school book axes,
legend={below,rows=1},
visualize as smooth line/.list={f1,f2},
f1={style=blue, style=very thick,label in legend={text=$\frac{1}{x-1}$}},
f2={style=green, style=very thick,label in legend={text=$\frac{1}{x^2 - 7x - 30}$}}
]
data [set=f1, format=function] {
var x : interval[0.5:4];
func y = 1/(\value{x}-1);
}data [set=f2, format=function] {
var x : interval[0.5:4];
func y = \frac{1}{x^2 - 7x - 30};
};
\end{tikzpicture}
%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%
\end{document}

Was muss ich ändern? Danke
func y = 1/(\value x - 1)
Das führt zu:
