Heat map - Length of Stay for 24 hr

[regowins]

Hi All,

For resource planning I have created a heat map showing the length of stay of a visiting person over a 24 hr period by day. For example if a person arrives at Mon 10 am and departs at Mon 2 pm I will get a flag of 1 for each hr from 10 am to 2 pm.  The question I have is how do I show a visit in the same 24 hr chart for a person that visited  on Mon at 11:45 pm and Departed the following day on  Tue

at 4 am.

The attached qvw works great for all people that arrived and left in the same 24 HR period. but I need a way to account for people that left the following day in the same chart for resource planning.

Working correctly with a 24 hr period

Need help with More than 24 hr period

1st visit  I would like a flag in 21 - 23 hrs and next day 0 - 1 hrs ( the next day flag needs to show in the same chart)

Hello Ashwin,

Why don't you work with timestamps istead of working with time and dates separately?

If you change your IntervalMatch script a bit to work with timestamps the timeline would be interpreted as a single continuous entity and your problem will be resolved automatically.

Hope this helps you.

Thanks, I am not sure how it would work with time-stamp. Can you give me a quick example. The other issue I had when with using time-stamp is if I you a time-stamp events of 12:00, 1:00, 2:00 and I have an interval from 12:10 - 2:17 I will only get a match on 1:00 and 2:00 but not 12 some reason since it falls outside the range.

Andrei - Sorry of the late response, this was a PERFECT example!!! I had initially tried to do it with timestamp but I did not think of converting to number. I also did not think of using the calendar gen to create the intervals. Again, THANK YOU for taking the time to put this example together!
