Hi Rouben,
I see. There is another sort of scaling which is typically working together
with a non-empty scale mode: the data scaling. Changing the domain
implicitly changes the *data* range - and that range is used to set up
internal coordinate transformations.
Adding 'disabledatascaling' will restore the proper layout. This, however,
will require a different 'scale' (like scale=100).
I have some ideas what's going on with that bug and I will report progress.
I typically create some unstable ready-to-run installation from pgfplots -
perhaps I can provide a fix to you eventually.
Best regards
Christian
