Base Pivot Table Off Different Ranges

I need to read consantly changing shift time/ covered data from a Pivot Tables pivot chart and populate this data into number of shifts covered/ uncovered. This information is then put into a chart over a 24 hour period (from 0700 to 0700). I have been populating the data from the pivot chart by hand by referencing the number of shifts in the covered line and dragging it to correspond to the shift time data part. I then have to do this for the uncovered shifts. As the data in the pivot chart is constantly changing, i need to do this data ransfer 'automatically'. I have started to look at and learn VBA, but i am getting nowhere fast. I enclose a worksheet (blank) to give you an idea fo what i am trying to do.
