Since @dcherian added Quiver plots in #4407, it's fairly simple to extend the functionality to streamplot().

For example (copying from @dcherian's unit test setup) ``` import xarray as xr from matplotlib import pyplot as plt

das = [ xr.DataArray( np.random.randn(3, 3), dims=["x", "y"], coords=[range(k) for k in [3, 3]], ) for _ in [1, 2] ] ds = xr.Dataset({"u": das[0], "v": das[1]}) ds["mag"] = np.hypot(ds.u, ds.v) ds.plot.streamplot(x="x",y="y",u="u",v="v", hue="mag") plt.show() ```
