After compiling the code I get: coordinate (0Y0.0e0],4Y0.0e0]) has been dropped because it is unbounded (in y)
. Here the solution was to specify a domain. I did it, hence I do not understand why I get this message.
\documentclass[border=0.5cm]{standalone}
\usepackage{pgfplots}
\pgfplotsset{compat=1.9}
\begin{document}
\begin{tikzpicture}
\begin{axis} [
xmin=0,xmax=1,
ymin=0,ymax=1,grid=major,
xlabel={$F_{\textrm{Kleb}}$},ylabel={$y/\delta$}, ylabel style={rotate=-90},
%width=6cm,height=4.5cm,
domain=0:1,samples=50]
\addplot [mark=none] {((1-x)/(5.5*x))^1/6};
\end{axis}
\end{tikzpicture}
\end{document}
restrict y to domain=0:1000
. The downside is that you'll have to ensure that the value is large enough to ensure the line is connected to the plot border.
