Hello clever people!
Can you help? I have a LONG list of people's movements (scan in / scan out), a sample shown below. I'd like to form a Histogram, counting the culmulative number of people in and out within 15 minute windows.
For example. If I started with 1000 people at 8am, what was my total at 8:15am, and at 8:30 mins (assuming more left or came back)... the data below is an example of the format, and extend throughout a 24hr period.
Thanks everyone!
