Hi Richard,
thanks for your interest in pgfplots. I'm glad you find it useful.
Concerning your question about label placement: the problem in this case
is that the default ylabel style defines rotations (and possibly shifts
as well). Using 'ylabel style={<options>}' means to /append/ something
to the default styles, i.e. it does /not/ clear the rotation.
The solution for your problem is to redefine the label style rather than
appending something to it.
This can be done using
every axis y label/.style={at={(current axis.above origin)},anchor=south}
instead of
ylabel style={....}
Alternatively, you can use the '*' version and use redefine 'every non
boxed x axis'. For example,
\pgfplotsset{
every non boxed x axis/.style={
xtick align=center,
enlarge x limits=false,
% x axis line style={-stealth}
},
}
would use the predefined styles, but without arrow heads.
Best regards
Christian
