ca['Date'] = pd.to_datetime(ca['Date'])

/usr/local/lib/python3.6/dist-packages/ipykernel_launcher.py:3: SettingWithCopyWarning: 
A value is trying to be set on a copy of a slice from a DataFrame.
Try using .loc[row_indexer,col_indexer] = value instead

See the caveats in the documentation: https://pandas.pydata.org/pandas-docs/stable/user_guide/indexing.html#returning-a-view-versus-a-copy
  This is separate from the ipykernel package so we can avoid doing imports until

import matplotlib.pyplot as plt
import seaborn as sns

# cc_df = cc_df.set_index('datetime')
ca.plot(x="Date", y=["ConfirmedCases", "Fatalities"])
plt.title('California')
plt.show()
