Hi everyone,

I asked a Likert scale type of question to about 1,000 people, asking them to choose a value between 1 and 5, with 1 being "strongly oppose" and 5 being "strongly favor". I asked the same question twice, before and after a treatment. I would like to plot an overlapping histogram of the distribution across the 5 possible answer for before and after.

I saw Nick suggesting something similar here (#4), but my data is different since I have two observations for each person (instead of the example with domestic/foreign).

Any suggestion?

Thanks!
