  • [NA] Closes #xxxx (remove if there is no corresponding issue, which should only be the case for minor changes)
  • [NA] Tests added (for all bug fixes or enhancements)
  • [NA] Tests passed (for all non-documentation changes)
  • [NA] Fully documented, including whats-new.rst for all changes and api.rst for new API (remove if this change should not be visible to users, e.g., if it is an internal clean-up, or if this is part of a larger project that will be documented later)

Added a resample example to reflect the DeprecationWarning: .resample() has been modified to defer calculations. Instead of passing 'dim' and 'how="mean", instead consider using.... There were also some missing parameters in the docs.

Made a minor edit to my rolling example which uses the parameter center. I can't remember if that parameter was there last time but I think it's useful to return the time value for the middle of window.

Added a groupby example. Not sure if this should go here. See text below for my motivation of putting an example in the docstring of the class/object.

I learnt xarray before I learnt pandas so these example will hopefully be useful to other beginners as it took me a minute to get the syntax right.

Whilst there are great examples of these functions in the docs, a google search of a function for example xarray rolling often returns the doc entry that that object. Having a little example there is helpful for me to get the syntax right. The key/value pair in a dictionary for example is very powerful and always takes me a few tries to get the entry right.
