I could use some help with adding tests and parameter checking if someone wants to help :)

``` python import numpy as np import xarray as xr

ds = xr.Dataset() ds.coords["x"] = ("x", np.arange(10)) ds.coords["y"] = ("y", np.arange(20)) ds.coords["t"] = ("t", np.arange(4)) ds["u"] = np.sin((ds.x - 5) / 5) * np.sin((ds.y - 10) / 10) ds["v"] = np.sin((ds.x - 5) / 5) * np.cos((ds.y - 10) / 10)

ds = ds * 2*np.cos((ds.t) * 2 * 3.14 /0.75)

ds["u"].attrs["units"] = "m/s" ds["mag"] = np.hypot(ds.u, ds.v)

ds.mag.plot(col="t", x="x")

fg = ds.plot.quiver(x="x", y="y", u="u", v="v", col="t", hue="mag") ```
