I'm trying to create a visualisation to see how many devices have connected to our application at certain times of the day. Of course, I can do this with regular bar / line graphs, but i'd like to visualise this with a heath map.

Heath map looking as following:

- Has the date histogram (Daily) on the X-axis
- The hours only on the Y-axis

I can't seem to find a way to display only hours on the y-axis. Is this possible?

Do you have a separate field for "hour\_of\_day" in your mapping? If not, you could create a scripted field for this in your index pattern settings. Then, you can split by date histogram for timestamp (x-axis) and by histogram with an interval of 1 for hour\_of\_day (y-axis). I can provide further instructions if necessary.
