Quick Table Calculations
Quick table calculations allow you to quickly apply a common table calculation to your visualization using the most typical settings for that calculation type. This article demonstrates how to apply a quick table calculation to a visualization using an example.
The following quick table calculations are available in Tableau for you to use:
- Running total
- Difference
- Percent difference
- Percent of total
- Rank
- Percentile
- Moving average
- YTD total
- Compound growth rate
- Year of year growth
- YTD growth
For more information about some of these, see Table Calculation Types.
How does a quick table calculation differ from a table calculation?
Quick table calculations are table calculations that you can apply quickly to your visualization in Tableau. They are applied to the visualization with the most typical settings for the calculation type you choose so that you can continue on with your analysis. With traditional table calculations, you can apply the same settings, but you must apply them manually.
Apply a quick table calculation to the visualization
Follow along with the steps below to learn how to apply a quick table calculation to a visualization.
Set up the visualization
Open Tableau Desktop and connect to the Sample-Superstore data source, which comes with Tableau.
Navigate to a new worksheet.
From the Data pane, under Dimensions, drag Order Date to the Columns shelf.
From the Data pane, under Dimensions, drag State to the Rows shelf.
From the Data pane, under Measures, drag Sales to Text on the Marks Card.
From the Data pane, under Measures, drag Profit to Color on the Marks Card.
On the Marks card, click the Mark Type drop-down and select Square.
The visualization updates to look like this:
Apply the quick table calculation
On the Marks card, right-click SUM(Profit) and select Quick Table Calculation > Moving Average.
Note: You can only perform quick table calculations on measures in the view.
A delta symbol appears on the field to indicate that a quick table calculation is being applied to the field. The colors in the visualization update to show the moving average of profit across the years.
(Optional) Customize the quick table calculation
On the Marks card, right-click Sum(Profit) and select Edit Table Calculation.
In the dialog box that opens, you can configure the following options:
The calculation type
How to aggregate the values
How to compute the calculation (how to address and partition the calculation)
For more information about these options, see Table Calculation Types and The basics: addressing and partitioning
The visualization updates as you make changes to the calculation. Highlighting and numbering are used to demonstrate how the calculation is being computed. For example, in the following image, the calculation is being computed across the table, for each State.
If this setting is changed, the visualization and highlighting update to indicate the change.
