Hi Xavier,
There is, indeed, a way to define that stuff globally: just collect all
your options which make up the global configuration and
place them into the document's preamble using \pgfplotsset:
\pgfplotsset{
every axis y label/.style={...},
<other common key>=<value>,
}
That's it. Settings assigned with \pgfplotsset{} constitue variables
which remain in effect until the end of the environment in which
\pgfplotsset was invoked or until the option has been reset manually.
In case you are also interested in my personal experience with such
global settings, here are a couple of best-practises:
a) always use a trailing comma (even for the last option)
b) properly indend your code with one key per line (allows simply
(un)commenting)
c) consider using named custom styles, i.e.
\pgfplotsset{
xavier standard/.style={
every axis y label/.style={...},
<other common key>=<value>,
},
}
\begin{document}
...
\begin{axis}[xavier standard]
...
Best regards
Christian
