Xarray is in the process of adding entrypoints for plotting backends in pydata/xarray#3640. I took a look at #319 which added entrypoint support for Pandas, and I noticed that .plot method is for Tabular data only:

What's the right path to adding the entrypoint for Xarray in hvplot? Should the .plot method in hvplot/plotting/__init__.py be
extended/generalized in order to return instances of hvPlot class instead of hvPlotTabular?

With some guidance, I am happy to submit a PR that addresses this issue 😃
