I have a short time range tstart – tend ( ≈ 90 seconds) and a list of points in time which represent events that occurred at that point. I'm looking for a concise visualization of these occurrences which shows (a) the number of events and (b) patterns like clusters or a bias for some point.
My ideas so far:
- a timeline with single ticks per event
- a timeline with discrete cells, colored corresponding to event density (cf. heat map)
- a circular timeline, like a clock; maybe even looking like a clock or stopwatch
(Sorry for the terrible image quality)
Any comments or other ideas?
Bonus question: How to extend these ideas if events belong to a small number (<10) of different categories?
