MCVE Code Sample

```python import numpy as np import matplotlib.pyplot as plt import xarray as xr

x, y = np.meshgrid(np.arange(12), np.arange(12)) z = xr.DataArray(np.sqrt(x2 + y2)) z2 = xr.DataArray(np.sqrt(x2 + y2)+1) ds = xr.concat([z,z2], dim = 'time') ds['time'] = [0,1]

f, ax = plt.subplots() ds[0].plot.contour(ax = ax, levels=[4], colors=['k']) f, ax = plt.subplots() ds[1].plot.contour(ax = ax, levels=[4], colors=['k']) ds.plot.contour(col = 'time', levels=[4], colors=['k']) ```

Problem Description

While drawing only one contour was fixed some time ago (#866), single contour plots in FacetGrid do not work for me.

Problem description

I received AttributeError: 'PydapArrayWrapper' object has no attribute 'shape' when I tried to open PydapDataStore. However, everything works when I use pydap instead of xarray.

Expected Output

255701612 MDU6SXNzdWUyNTU3MDE2MTI= 1555 TypeError: DataArray.name or Dataset key must be either a string or None for serialization to netCDF files kuchaale 6815953 closed 0     2 2017-09-06T18:34:04Z 2017-09-07T07:38:46Z 2017-09-07T07:38:46Z NONE      

Consider the following gist where I receive the following error: TypeError: DataArray.name or Dataset key must be either a string or None for serialization to netCDF files.

I think that I run into a bug when DataArray.name is checked by check_name function. I think that k in the corresponding for loop actually represents DataArray not DataArray.name itself. Thus, I suggest something like this to fix it: for k in dataset: check_name(k.name)
