This is a follow-up to a previous question of mine, with a slight addition. I would like to loop over data in a file and give the plot styles as a list. In the old question I gave only a color and an index and Christian Hupfer came up with a working solution as did, with a slight variation, cmhughes.
Now, I would like to specify the style more precisely. For example, I would like to be able to draw dotted or dashed lines like in the following MWE
\documentclass{article}
\usepackage{xcolor}
\usepackage{pgfplots}
\begin{document}
\begin{tikzpicture}
\begin{axis}
\pgfplotsforeachungrouped \foridx/\forcol/\forstyle in {1/black/solid,2/red/dashed,3/green/dotted,4/blue/solid,5/orange/dotted}{
\expandafter\addplot\expandafter[\forcol,\forstyle]{x^\foridx};
}
\end{axis}
\end{tikzpicture}
\end{document}
If I leave out \forstyle and the third arguments in the list, I get Christian Hupfer's solution which is working. Like this, it produces many errors:
! Undefined control sequence.
<argument> ...pgfplots@foreach@loc@TMPb \forstyle
l.9 }
The control sequence at the end of the top line
of your error message was never \def'ed. If you have
misspelled it (e.g., `\hobx'), type `I' and the correct
spelling (e.g., `I\hbox'). Otherwise just continue,
and I'll forget about whatever was undefined.

With the linked code snippet from cmhughes, I couldn't get it to work either with similar errors (probably the same problem)
So I tried to give the arguments to \addplot in a list:
\pgfplotsforeachungrouped \foridx/\forstyle in {1/{black,solid},2/{red,dashed},3/{green,dotted},4/{blue,solid},5/{orange,dotted}}{
\expandafter\addplot\expandafter[\forstyle]{x^\foridx};
}
This compiles but it produces only a solid black line (it loops only over the first element)
In fact, I could not get any example with three variables working. How do I use pgffor with three or more variables?
