Plotting with timedelta64 axis

[kcajf]

Pandas plotting has nice handling of timedelta64 axes - xarray seems to just plot these as integer nanoseconds. Would be great to have this functionality in xarray:

data = xr.DataArray(np.random.random(100), coords=[('td', np.arange(np.timedelta64(0), np.timedelta64(10, 'h'), np.timedelta64(6, 'm')))])

data.plot.line(x='td')

plt.figure()

data.to_pandas().plot()

looks like matplotlib doesn't add nice labels for timedelta64:
plt.plot(data.td.values, data.values) looks like data.plot().

Pandas is doing it's own thing here: https://github.com/pandas-dev/pandas/blob/68b1da7f53f043b21e3f722e8872e19941a10250/pandas/plotting/_converter.py#L1125
