That is not the xlabel docstring.

Since there are four of them, I'm not sure floats was necessarily a typo. A quick search shows that we do both "tuple of [plural]" and "tuple of [singular]" in various places so we have not standardised.

I don't think it really matters as both variants are equally understandable. If we want to standardize, I'd slightly favor "tuple of float" in analogy to "tuple of str".

Thank you both for the feedback and the clarification!

It sounds like this is more of a style preference with no established standard yet. Since I'm new to contributing, I'm happy to follow your lead.

If the consensus is to leave the original wording as is, I am perfectly happy to close this pull request. No problem at all.

Thanks again for your time!

Ah sorry, I should've renamed this before merging.

That's fantastic! Thank you so much for the review and for merging it.
