I am trying to graph attendance over time for a large number of events. This data is presented by week, so I have attendance per week for each event. The events take place in multiple locations, so I want to be able to see how attendance compares at each venue by graphing the lines on top of each other. So far, I have only been able to display this data cumulatively.
How would I go about this? Thanks in advance!
I'm using Office 365 for Mac.
