I want to use markers form \usetikzlibrary{plotmarks}, like: pentagon*, diamond*, square* and triangle* in the title of the plot. They work as markers in the plot but i get an error when in want to include them in the title (instead of the "x" in \mathbf{})
This is my code:
\begin{filecontents*}{data.txt}
b d c
1 a 2
2 b 4
3 c 6
4 d 8
5 e 10
6 f 12
7 g 14
8 x 16
9 x 18
\end{filecontents*}

\pgfuseplotmark{square*} works but it also changes the title.

${\color{red}\pgfuseplotmark{square*}}=\SI{10}{\kilo\Hz}$,

It looks like this:
After using \def\showmark#1{\tikz[baseline]\node[red]{\pgfuseplotmark{#1}};} the problem with the y-alignment is fixed, but the title is not centered anymore.
Using \showmark{square*}=$\SI{100}{\kilo\Hz}$ instead of \showmark{x}=$\SI{100}{\kilo\Hz}$ leads to:
\pgfuseplotmark{square*}(cf. e.g. http://tex.stackexchange.com/questions/64567) works here, though the vertical alignment is off. – Torbjørn T.

I don't have a fix at the moment, but I'm sure someone does. – Torbjørn T. Jan 11 '17 at 12:15
