Hello! I need to compare last month's and this month's data. Specifically, i just want to get a count of all records whose stage changed. I am blending two data sources: This Month's Opportunities and Last Month's Opportunities. I've created the following two formula's in "This Month's Opportunities" data source:
If Percent Complete is NULL in Last Month's Opportunities, return .1
I would like to summarize this finding by creating a bar chart similar to:

However, I can't get Tableau to give me a summary by the Stage Change Indicator field without providing additional information such as the old and new stage. Anyone have any idea what I can do to get the chart above instead?
