I agree, and I was aware of this problem. It arises from the fact that 
the "tight" state is not saved, as I think it should be. I will look 
into fixing that.

That seems to me like a more complex and confusing solution than saving 
the "tight" setting, and keeping it until it is explicitly changed by 
its own setter, by autoscale_view, or by margins. The default for 
autoscale_view will then be to change "tight" only if the kwarg is 
provided and is not None.

Eric,
Just a minor concern about "locator_params" implicitly calling "autoscale_view".
For example,
ax1 = subplot(121)
ax1.plot([1,2,3])
ax1.locator_params("x", nbins=5)
ax1.margins(0.1, tight=True)
ax2 = subplot(122)
ax2.plot([1,2,3])
ax2.margins(0.1, tight=True)
ax2.locator_params("x", nbins=5)
Same commands are applied to each subplot but with different order,
and the results are different.
"ax.2locator_params("x", bnins=5)" implicitly calls
"ax2.autoscale_view(tight=False)", overriding tight=True in margins
call.
And I think this is a bit confusing.
I understand that autoscale_view depends on locator. Still at least
some option to prevent calling "autoscale_view" may be needed?
