Is there an xarray way to make a surface plot, like matplotlib's plot_surface()? I didn't see one on a quick skim, but expect it should be fairly easy to add, following the style for contour(), pcolormesh(), etc.? For the matplotlib version, see https://matplotlib.org/stable/gallery/mplot3d/surface3d.html.

823290488 MDExOlB1bGxSZXF1ZXN0NTg1Nzc0MjY4 5003 Add Dataset.plot.streamplot() method johnomotani 3958036 closed 0     2 2021-03-05T17:41:49Z 2021-03-30T16:41:08Z 2021-03-30T16:41:07Z CONTRIBUTOR   0 pydata/xarray/pulls/5003

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() ```
