Change thousands separator in pfgplots' ticklabels to space

Question

I am sure that I am repeating an old question, but I couldn't find it in the Tex Exchange browser.

I am using french mathematics nomenclature and thousand separation is a space like this 1 000 and not by a coma 1,000 (that means 1 in french). The pgfplots package make appear numbers in the thousand separation as english typesetting and I want to change it.

Illustration :

Try add into axis option ticks={style={/pgf/number format/set thousands separator={\,}}},. — Zarko, Jan 05 '16 at 12:15
In your axis labels, n and r should probably be replaced by $n$ and $r$, respectively. — pluton, Jan 05 '16 at 14:46

You can use the following key:

\pgfkeys{/pgf/number format/.cd,1000 sep={\,}}

Full MWE

\documentclass{article}

\usepackage{pgfplots}

\begin{document}

\pgfkeys{/pgf/number format/.cd,1000 sep={\,}}
\begin{tikzpicture}
    \begin{axis}
    \addplot {100*x^2};
    \end{axis}
\end{tikzpicture}
\end{document}

If you're just changing one key, you can use

\pgfkeys{/pgf/number format/1000 sep={\,}}

as mentioned by Jake in the comments.

In case you're often switching languages with its various number formats you'll probably use the siunitx package to do so in text. To synchronize your siunitx settings with the ticklabels, you could use:

\documentclass{article}

\usepackage{pgfplots}
\usepackage{siunitx}
\sisetup{group-digits=true,
         group-four-digits=true,
         group-separator = {\,},
         output-decimal-marker = {,}}

\pgfplotsset{
  siunitxlabels/.style={
    /pgfplots/typeset ticklabel/.code={\pgfmathparse{\tick}$\num[zero-decimal-to-integer]{\pgfmathresult}$},
  },
}

\begin{document}

\begin{tikzpicture}
    \begin{axis}[siunitxlabels
    ]
    \addplot {100*x^2};
    \end{axis}
\end{tikzpicture}
\end{document}
