Please see attached my Tableau Workbook. I have a Pie Chart that I'd like to connect and update two different data sources to using the Parameter Included (Parameter_2). Also, I'd like the Pie Chart to Update Based on whether Total Balances is selected or Total Fan Base (Parameter_1). I was a little afraid to Join the Data as they don't have anything in common other then Archive Dates and even then in the full set, the Dates may differ. I looked into Data Blending but couldn't get it to work and am slightly frustrated. Thanks for all your help!
