Hello DIVYA TIKKISETTI,
Attached is a sample view for of this sort of two levels of data. The sample utilizes the Tableau "Superstore" data set and in this case I have created a calculation to capture just the sales from a selected region so that it can be compared to all Sales in a view.
If [Region]=[Select Region] then [Sales] END
This example uses a parameter in both a bar chart and a crosstab as you have setup. I prefer the bar chart since it is much easier to see big discrepancies.
I hope this helps.
I am using tableau desktop 9.3. The attached workbook is of higher version than that, so throwing error from my side. Please help.
