Would it make sense to make it (DA plotting interface) a bit more pandas-compatible by supporting `style`? Given that it copies pandas syntax like `arr.plot.line()` anyway... 

Also, if `plot()` is meant to be a thin wrapper around matplotlib, it should support positional arguments, since you can do `plt.plot(x, y, '.-')` just fine, but `da.plot('.-')` fails complaining about unexpected positional arguments.

Currently, neither of the two options above work, making DA plot interface inferior to both raw matplotlib and pandas.","{""total_count"": 0, ""+1"": 0, ""-1"": 0, ""laugh"": 0, ""hooray"": 0, ""confused"": 0, ""heart"": 0, ""rocket"": 0, ""eyes"": 0}",,423774214

ping @pydata/xarray for opinions on adding the `style` kwarg. I prefer that to the non-explicit `da.plot('.-')` syntax.","{""total_count"": 0, ""+1"": 0, ""-1"": 0, ""laugh"": 0, ""hooray"": 0, ""confused"": 0, ""heart"": 0, ""rocket"": 0, ""eyes"": 0}",,423774214

matplotlib only knows about numpy arrays so `plt.plot(arr, ...)` will act like `plt.plot(arr.values, ...)` by design.

the way to do what you want is using kwargs `arr.plot.line(marker='.', ls='-')`. `plt.plot` doesn't accept `fmt='.-'` so there's not much we can do to support that format string syntax.

Can you open a PR to improve the documentation on these points please?","{""total_count"": 0, ""+1"": 0, ""-1"": 0, ""laugh"": 0, ""hooray"": 0, ""confused"": 0, ""heart"": 0, ""rocket"": 0, ""eyes"": 0}",,423774214
