Tableau Table Calculations

Create a Percent of Total in Tableau That Isn't Affected by Filters

As you likely know from using Table Calculations in Tableau, they only compute against the marks displayed in a worksheet. Check out this webinar in you need a refresher.

That means when a filter is applied to the worksheet, a table calculation will update to reflect only the data present in the worksheet.

Tableau Table Calculations - What Does “Specific Dimensions” Mean?

You may have noticed that under “Compute Using” in the Table Calculation dialogue box there is a section called “Specific Dimensions” where you would normally select a scope and direction. You generally only need to use Specific Dimensions when you have 3 or more dimensions in the view.

Comparing Year Over Year in Tableau

When calculating growth rates from one date period to another, it’s important to compare apples to apples. For instance, when building a graph in Tableau to compare quarterly sunscreen sales in Seattle, I probably wouldn’t want to compare Q3 Sales (July - September) to Q2 Sales (April - June) because there will be more sales in Q3. The product has a cyclical sales cycle. Instead, I would rather compare Q3 Sales of this year to Q3 Sales of last year to more accurately understand growth rates.
