Description
MCVE Code Sample
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(x**2 + y**2))
z2 = xr.DataArray(np.sqrt(x**2 + y**2)+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'])Output
Expected Output
Problem Description
While drawing only one contour was fixed some time ago (#866), single contour plots in FacetGrid do not work for me.
