I know that the subject may not be explicit, but I (still) don't know how to describe my problem in few words.
Here's the thing :
I want to know for how many hours, 80% of patients went off my hospital .
For example :
I have 10 patients who went out during a day , the first patient went out @ 10:00 and the 8th one @ 17:00 ,so it took 7 hours so see 80% of patients out.
I have patients who go out from my hospital at any time of the day. (the time and dates are stored in a field).Now I really don't know how to solve the problem. It's been 2 days that I look a magic trick.....but in vain.
Of course ,I have the data every time a patient goes out.
And this info , have to be display in a table chart....
If you can pull me out from this hole,it'd be very nice.....
