When a time series only has one observation, the HierarchicalPlot.plot_hierarchically_linked_series fails. The error arises because of the following line,

hierarchicalforecast/hierarchicalforecast/utils.py

Line 124 in 52a3525

df_plot = Y_df.loc[series].set_index('ds')

In that case, Y_df.loc[series] returns a pd.Series object instead of a pd.DataFrame object and therefore the index cannot be set.
