Plot barchart with lists as values in columns

I have a dataset that looks like this: dataset With this code:

    df_lists = df[['FC-Final [l/100km]']].unstack().apply(pd.Series)
    df_lists.plot.bar(rot=30, cmap=plt.cm.jet, fontsize=8, width=0.7, figsize=(8,4),
                  title='Fuel Consumption per route', ylabel='FC-Final [l/100km]')

I manage to generate this graph mybarchart

I am trying to add the values from the 'Route' column as xticks instead of the current ones but I get this error:

ValueError: Missing category information for StrCategoryConverter; this might be caused by unintendedly mixing categorical and numeric data

My questions:

1. How can I add the values from 'Route' column as xticks?
2. Is it possible to add a secondary y-axis so that each bar level corresponds to both the 'FC-Final [l/100km]'(main y-axis) AND the 'distance [km]'(secondary y-axis)?
3. Can I also display the values from 'time [min]' column right on top o each corresponding bar?

I face trouble because as seen in the dataset, some routes have 2 different fuel consumptions and time and some others have 3 or even 1...
