    Count 'active' people in a Gantt chart?

    Mark Ewing

      I have data for people scanning into and out of a building.  I have visualized this using a Gantt chart by starting with the IN time and using the length of visit as the size.  This is a great visualization and has been really helpful in identifying some interesting patterns.  I'm curious though, is there a Table calculation that would, by minute, count the number of people in the building?  I can think of some inefficient ways of doing this in R, but I'm curious if this is easy to do in Tableau.  Thanks!
