Re: Data Studio and Google Sheets
Hi Dick -- apologies for taking so long to respond here. I think I understand your question now, and I believe this has to do with the way that your data is organized in your data source. Instead of one column for each metric, you should try to organize your data in the way I show below. Restructuring in way will let you add up to ten pie slices (note that you will have to filter the chart by week if you want to see just a single week).
Hope that helps -- apologies again for delay and let me know if you have any other questions here!
