Answer 1

Assuming your data frame is named df and you don't require the year to show up, Try using

df = df.reset_index()
df = df.set_index('Flexible working Age')

Then drop the year and plot the bar graph normally. You can do this using a copy of the data frame as well

data = df.copy()

In case you want to retain the original data frame.

You can label the bars on top with the year if you want the year to be seen.

Use a loop and use

plt.annotate()

I don't have any of your code so I can't help you anymore.
