For details, See Configure total aggregation. However,īe aware that your results may be unexpected when using other aggregations,Įspecially custom aggregations. Products, the grand total will be the sum of the sums of profit.įor aggregations such as SUM, you can easily verify the grand totalīecause a summation of a group of sums is still a summation. In this case, totals are based on the underlying data rather than the data in the view.įor example, if you are totaling the SUM(Profit) for several When you turn on grand totals, the initial values are computing using the current aggregation for the fields in the view. This kind of total is sometimes referred to as a two-pass total, because the average you see in the grand total column is aggregated twice-once to derive the column or row value, and then again across column or rows to derive the grand total. Now the average is performed on the values you see, and not on the disaggregated date in the data source: To display a result of this type, from the Analysis menu choose Totals > Total All Using > Average. Fortunately, you do not need to perform two operations. Then the results for each region must be derived, by averaging the results for the individual marks. To see totals that correspond to the numbers you see in your view requires two averaging operations in Tableau: first, values for the individual marks (or cells) in the view must be derived-for example, by averaging all values that have the properties Ship Mode = First Class, Category = Furniture, and Region = Central. The result is derived by averaging all values that have the properties Ship Mode = First Class, Category = Furniture, without regard to region. In this case there are more than four numbers to average, perhaps many more. The discrepancy is due to the fact that Tableau is averaging the data in the underlying data source. But if you compute the average for the four values you see in the row ($329, $306, $390, $348), the result comes to $343.25, not $339. The average that you see at the right of the first row under Grand Total is $339. When you first turn on grand totals, the totals are computed using disaggregated data in the underlying data source.

Source, and locally if you are connected to an Essbase data source, using Server if you are connected to a Microsoft Analysis Services data Note: By default, totals are computed on the In theįigure below, only column totals are calculated because the table You can also display totals for graphical views of data. Grand totals cannot be applied to continuous dimensions. See Grand totals and aggregations for more Measures must be aggregated – The aggregation determines You can calculate grand totals for columns. The view must have at least one header – Headers areĭisplayed whenever you place a dimension on the Columns shelf For information how to move where totals appear, see Move totals. Column grand totals appear automatically at the bottom of the visualization. Row grand totals appear automatically on the right-side of the visualization. In the Analytics pane, under Summarize, drag Totals into the Add Totals dialog, and drop it over either the Row Grand Totals or Column Grand Totals option. This article demonstrates how to show grand totals and subtotals in a visualization, as well as how to customize how those totals are calculated and where they appear in the visualization.
