This should be a very simple question.
\documentclass{article}
\usepackage{tikz}
\usetikzlibrary{decorations.text}
\begin{document}
\begin{tikzpicture}
\draw[-stealth,postaction={decorate,decoration={text along path,text align=center,text={this way}}}](0,0)to[bend right=45] (2,0){};
\end{tikzpicture}
\end{document}
I want the text to be below the line, not above. Is it possible?
