Thank you very much.
In addition to what your did, for event 1, I would like to draw a horizontal
line connecting from day 1 to day 2 to day 3 to day 4.
Then, for event 2, I would like to draw a horizontal line connecting from day 1
to day 2 to day 3 to day 4.
Similarly for events 3, and 4. Is that convenient to do?
