How can you display the percentage of total in Tableau?

To display the percentage of total in Tableau effectively, creating a calculated field or using the Quick Table Calculation feature set to "% of Total" is the appropriate method. This approach allows you to dynamically calculate the percentage contribution of each value relative to the total sum of the selected data points, providing a clear visualization of each part's proportion within the whole.

Using the Quick Table Calculation for "% of Total" simplifies the process, as Tableau automatically performs the necessary computations based on the data context. It ensures that when the dimensions or measures change, the percentage calculations will adjust accordingly, maintaining accuracy and relevance in the analysis.

The other methods would not yield the desired result. Simply summing all values does not provide a contextual percentage; it only gives the total of the values. Dividing each individual value by the total number of data points could lead to incorrect outcomes unless it's performed correctly in relation to the aggregated total. Filtering to show only top percentages, while helpful in some analyses, does not inherently display the percentage of the total across all values, falling short of conveying the complete picture necessary for understanding contributions to a whole.
