Turns out this is more difficult than I thought... I did some digging into where these doc pages are defined (e.g. http://xarray.pydata.org/en/stable/generated/xarray.Dataset.argmin.html) and realized they are auto-generated from a template in core/ops.py, which is the same for various "reduce" functions, most of which are more self-explanatory like max or min. Creating more useful doc page for argmin/argmax would, I believe, require writing a new template for them, which would in turn require separating argmin and argmax from "NAN_REDUCE_METHODS" and writing a new "inject" function for them. This would mess up a lot of other places that use the "inject_reduce_methods" function. Not sure if this is worth the effort especially since @shoyer left a todo note saying he's going to rewrite this module anyway.

It might still be worth adding an example use case of argmax/argmin, maybe finding the dates of the highest and lowest temperatures in the toy weather data example.
