I am new to Tableau and I have created a crosstab that shows a count of items per type. I want to add a column to my table. I need to know the percentage of the whole - I looked up a couple of things but I can't seem to find this exact problem.
Type |Count |% of Whole
-----------------------------------
A |10 |1%
B |99 |9.9%
C |256 |25.6%
D |300 |30%
E |335 |33.5%
After reading some I think my issue is that I am not sure how to derive a calculation that is going to give a TOTAL # of Types. In Excel I would take the row value divided by the sum of all rows. Additionally I am fairly certain that this will lead to an issue once I filter this table - not sure I know how to preserve the percentages with filters.
I am using Tableau 9.2. Thanks in advance for any help.
