What is the Power Fx GroupBy Function?
The Power Fx GroupBy function is a function that groups data based on a specified column or columns. It returns a table that contains the grouped data and the summaries of the data. The summaries can be in the form of count, sum, average, minimum, maximum, and more.
How to Use the Power Fx GroupBy Function
Before we dive into how to use the Power Fx GroupBy function, let’s take a look at the syntax of the function. The syntax for the Power Fx GroupBy function is as follows:
GroupBy(Table, GroupColumns, Aggregates)
– **Table**: The table that you want to group.
– **GroupColumns**: The column or columns that you want to group on. This can be a single column or multiple columns separated by a comma.
– **Aggregates**: The summaries that you want to calculate. This can be a single summary or multiple summaries separated by a comma.
Now let’s take a look at an example of how to use the Power Fx GroupBy function. Suppose we have a table named “Sales” that contains the following columns: “Region”, “Category”, “Salesperson”, and “Sales”. We want to group the data by “Region” and “Category” and calculate the sum of “Sales” for each group. Here’s the formula we would use:
GroupBy(Sales, "Region", "Category", "Sum(Sales)")
This formula would return a table that contains the grouped data and the sum of “Sales” for each group.
