Using a pivot table I need to create a running average of values for the last
10 days. It's easy to display the averages for each day and filter off
everything but the last 10 days BUT... I can't get a running average working.
The goal is to develop a dynamic graph/chart that shows the average with a
trend line for the running average to see if things are improving.

There is a built in function for running totals but I need the average of
the previous numbers not the totals.

I am somewhat familiar with calculated fields but am not smart enough to
pull it all together to make this work.

Any help would be appreciated.
