I want to build a pivot cart that will go off this table that contains month to month employee performance grades.
The table headers are months (1/1/2021, 2/1/2021, 3/1/2021, 4/1/2021...)
The table rows are the staff members.
The values for each cell is the staff grade for that month out of 100.
I wanted to create a pie chart that will have a slicer that for the months so I can get a monthly average. If i wanted a 3 month or 5 month or all time average score. And it will demonstrate with the pie chart.
