There was a problem hiding this comment.
Thanks @stephenworsley ❤️
I'm satisfied that:
- We already have enough test coverage to allow for the new behaviour
(since you had to change an expected result as part of this change, for a valid reason) - Nothing has broken
(since all the tests pass)
Please could you address my one comment, and I think we'll be done 🙂

Description
Addresses #3848 (and the duplicate issue #3821).
The replacement formatter is not designed to be an exact copy of IndexFormatter since it seems that IndexFormatter can be considered bugged. Specifically, IndexFormatter would add a duplicate of the label at the 0 tick to the -1 tick. This behaviour was being accounted for by our tests, which have been changed to reflect the new behaviour. The new behaviour also relies on ticks being located precisely on integers (the IndexFormatter would perform some rudimentary rounding operations). This should always be the case since the locator is
MaxNLocator(integer=True).
