Columns to compute total rows in: Specify a dimension columns on the left side, and the corresponding total rows label on the right side (for example if you have a a dataset with sales by country and that you want to compute the total sales of all countries, you will specify your country column and give a label such as “Total countries”). You can add several couples to compute total rows in several columns.
Columns to aggregate: in this section of the form you can specify one or more columns to aggregate, with the corresponding aggregation function to be applied (equivalent to SUM(MY_COLUMN) for example in SQL, or to my_column: { $sum: { $my_column } } in Mongo). You can add columns to aggregate by clicking on the button Add aggregation.
- Columns: the columns to be aggregated (you can apply the same aggregation function to several columns at once)
- Function the aggregation function to be applied (sum, average, count, count distinct, min, max, first or last)
(Optional) Group by: Optional, if you need to apply the total rows computation by group of rows (see the second example below for illustration)
