pgfplots axis description near arrow for non boxed axes

Question

In PGFPlots, I'd like to set the default axis description location near the arrow for non boxed axes and otherwise keep the existing default of placing the axis description halfway between both ends of the axis. For example, take the following code:

\documentclass{article}

\usepackage{tikz}
\usepackage{pgfplots}
\pgfplotsset{compat=1.17}

\pgfplotsset{%
  every axis x label/.style={%
    at={(ticklabel cs:0.95)}, anchor=near ticklabel,
  },
}

\begin{document}
\begin{tikzpicture}
  \begin{axis}[
    xlabel={$x$},
    ylabel={$y$},
    axis x line=bottom,
    axis y line=left,
    ]
    \addplot[
    domain=-2:2,
    samples=100,
    ] {x^2};
  \end{axis}
\end{tikzpicture}
\end{document}

which produces:

The every axis x label sets the axis description position regardless of whether the axis is boxed or non boxed (comment out axis x line to see this). There's a every non boxed x axis key, but I believe this is for the axis line, not the description. I wasn't able to find a every non boxed axis x label key, or something similar. Of course, I could do this on a case-by-case basis (which is what I've been doing), but I'd prefer to make this a default. Is this possible?

Answer 1

I think if you put the every axis x label style inside the every non boxed x axis, it works. And duplicate it in every non boxed y axis as well, if you want that.

\documentclass{article}
\usepackage{pgfplots}
\pgfplotsset{compat=1.17}

\pgfplotsset{%
every non boxed x axis/.style={
  every axis x label/.style={%
    at={(ticklabel cs:0.95)}, anchor=near ticklabel,
  },
},
every non boxed y axis/.style={
  every axis x label/.style={%
    at={(ticklabel cs:0.95)}, anchor=near ticklabel,
  },
},
width=7cm, height=3cm % just for example
}
\begin{document}
\begin{tikzpicture}
  \begin{axis}[
    xlabel={$x$},
    ylabel={$y$},
    axis x line=bottom,
    axis y line=left,
    ]
    \addplot[
    domain=-2:2,
    samples=100,
    ] {x^2};
  \end{axis}
\end{tikzpicture}

\begin{tikzpicture}
  \begin{axis}[
    xlabel={$x$},
    ylabel={$y$},
    ]
    \addplot[
    domain=-2:2,
    samples=100,
    ] {x^2};
  \end{axis}
\end{tikzpicture}

\begin{tikzpicture}
  \begin{axis}[
    xlabel={$x$},
    ylabel={$y$},
    axis y line=left,
    ]
    \addplot[
    domain=-2:2,
    samples=100,
    ] {x^2};
  \end{axis}
\end{tikzpicture}

\end{document}
