When using a half space (\,
) as the thousangs separator it is common to only start using it for numbers larger than 10000. This is reflected, e.g., in the siunitx package:
\SI{1000}
becomes 1000\SI{12345}
becomes 12 345
However, pgfplots appears to only offer
\pgfkeys{/pgf/number format/.cd,1000 sep={\,}}
which adapts the thousands separator for all groups of three digits. Is there a way to change this behavior, matching the one specified above?
