# Calcalate hours active

Posted on 2013-12-17

Hi Experts,

I have a spreadsheet which contains a (dynamic) value for "hours worked".  From this value (let's say 12) I want to plot a graph showing the hours worked, against all 24 hours in a day.

The middle of the shift is always 01:00AM

So, if hours worked = 12 the graph should show that the shift began at 19:00 and finished at 07:00.

It should be assumed that 1am always represents the middle of the shift.  I only want to show whole hours if possible (i.e. I don't want the graph to have to show 30 minute slots, caused by dividing the shift lenght by 2), but this is not a show-stopper.

Help!!!!

Thanks :)

You can try a stacked bar or stacked column chart showing a transparent bar or column for the the off hours and a colored one for the working hours.

If A1 contains hours in "time" format then you can use

=25/24-INT(A1*12)/24

Sorry, so thanks for this - I now know the start and end times of the shift.

Can you show me how to plot this?

Did my formula not work or you did not try it?
