Dear Denis,
the problem is caused by the fact that pgfplots internally opens a
*second* tikzpicture... and the every picture style is applied twice.
I am not sure if this is a bug (it probably is) - anyway, a work-around
could be to try
\tikzset{
every picture/.style={scale=0.7,every picture/.style={}},
}
This resets the style after it has been applied for the first time, i.e.
nested pictures are not affected.
Alternatively, you could try one of the scaling styles of pgfplots (like
small,tiny, etc) -- which apply only to pgfplots, of course (but they
use the correct fonts).
I hope this helps.
Best regards
Christian
