I'm not sure exactly what this kind of chart is called, but I'm going to call it a "clock plot"
Basically I want to use it to visualize events that happen at certain times of day over say the course of a month. The idea is to record the time that this particular event occurs during the day and plot it on the graph. That way at the end of the month, I can visualize the frequency of the events over time. Is something like this even possible in Excel and if so, how could I do it? Thanks
