My data source is an 'outer join' of data from three distinct excel sheets with non-overlapping data. Each sheet has the same fields for filtering and the same two dimensions for the desired graph, ID and Reason. I want to create a basic bar chart that has the Reasons across all three sheets on a single horizontal axis and a CountD(ID) on the vertical axis.
How can I combine the three separate dimensions into one dimension? Should I use a calculated field?
Let me know if you need further information.
