393742068 MDU6SXNzdWUzOTM3NDIwNjg= 2628 Empty plot with pcolormesh in the notebook 4711805 closed 0     3 2018-12-23T11:21:48Z 2020-12-05T05:06:36Z 2020-12-05T05:06:36Z CONTRIBUTOR      

Code Sample

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

a = np.ones((4000, 4000), dtype=np.uint8) a[:1000, :1000] = 0 lat = np.array([0-i for i in range(a.shape[0])]) lon = np.array([0+i for i in range(a.shape[1])]) da = xr.DataArray(a, coords=[lat, lon], dims=['lat', 'lon'])

da.plot.pcolormesh() ```

Problem description

The code above shows an empty plot in a notebook (but not in the console).

Expected Output

If I replace da.plot.pcolormesh() with da.plot.imshow() or plt.pcolormesh(a), it works fine. Also, if I decrease the size of the array, it works.

Output of xr.show_versions()
