I was recently asked for assistance with this request:
Hi Steve,
I am trying to make a hypnogram with data that we collected over the course of a day. I want the y-axis to denote wake (W), other (O), and sleep (s) with just three tick marks. The y-axis should represent the time spent in these states.
A hypnogram plots sleep patterns over time and is used to asses a person’s wake/sleep behavior at night (or during the day). It is used for diagnostic and treatment purposes for individuals with sleep disorders.
Some sample data:
| W | 8:20:49AM | 8:21:04 |
| O | 8:21:05AM | 8:21:24 |
| W | 8:21:25AM | 8:21:54 |
| S | 8:21:55AM | 8:23:43 |
| W | 8:23:44AM | 8:23:57 |
| O | 8:23:58AM | 8:24:44 |
| W | 8:24:45AM | 8:28:11 |
| S | 8:28:12AM | 8:29:34 |
| W | 8:29:35AM | 8:30:31 |
| S | 8:30:32AM | 8:35:26 |
The second set of numbers is when the state ended.
Thank you,
Anna

Even though you can use the tutorials above to help with this Excel challenge, there is a trick to working with a Time Series in Excel. So it might not be a easy as it may first appear.
Give it a shot and let me know if you were able to solve this challenge. I was able to solve Anna’s request and she was able to automate it with the formulas you see in the tutorials above. I might even get a mention in her publication if it is accepted 🙂 Way cool!

Hi Steve.

Hi,
I was trying something very similar with a different time scale (in 30s intervals) and numbers instead of Sleep Stage letters, however I always get diagonal vertical lines and I can not get it properly done. Can you help me with this Steve?
Columns extend up to 2400 cells, so a way to semi-automatize the process would be very apreciated. Here is a brief example of the data:
20.28.00 3
20.28.30 3
20.29.00 4
20.29.30 1
20.30.00 2
20.30.30 2
20.31.00 3
20.31.30 3
20.32.00 3
20.32.30 3
20.33.00 1
20.33.30 1
20.34.00 1
20.34.30 2
20.35.00 3
20.35.30 3
20.36.00 3
20.36.30 3
20.37.00 4
20.37.30 5
20.38.00 5
20.38.30 5
20.39.00 5
20.39.30 5
20.40.00 1
20.40.30 2
20.41.00 2
Thanks in advance!

Hi Steve,
I was trying to make something very similar to this hypnogram, the difference is the time scale, my data consists in 30 s intervals and instead of the Sleep Stage I have numbers.
I already tried to make it following every tutorial and I always get diagonal lines instead of vertical lines.
Here is some example data:
20.11.30 1
20.12.00 1
20.12.30 2
20.13.00 2
20.13.30 2
20.14.00 3
20.14.30 3
20.15.00 2
20.15.30 2
20.16.00 1
20.16.30 2
20.17.00 1
20.17.30 2
20.18.00 1
20.18.30 1
20.19.00 1
20.19.30 2
20.20.00 3
20.20.30 3
20.21.00 1
20.21.30 1
20.22.00 1
20.22.30 2
20.23.00 1
20.23.30 2
First column is the time and the second is the stage.
The thing is that I have more than 2400 values in each column…
Thanks in advance!

Hi Leo,
You only need where the value changes. I used your data and my formulas from the post and got this:
Remember that you also need to use a XY Scatter Chart
