Aggregate functions in a Canvas Power App | Using on SharePoint Lists

Aggregate functions have one of the most common applications while building your Canvas Power App.

In this simple example, we’ll try to make common Aggregate Functions like Max, Min, Sum & Average work.

There are 2 more advanced Aggregate Functions, StdevP for Standard Deviation and VarP for Variance. (It might not make full sense in this post, but I added them anyway to see how we can apply for formula 😊 I’m sure your use-case will make more sense!)

SharePoint List

Let’s say, my SharePoint list looks like this. Scores of some people and their ranks

And I’m using Data Table to populate this into my Canvas Power App

Formulas

Here’s how I used for Formulas to use the Aggregate functions on the SharePoint list data I populated in my Canvas Power App

For all the Formulas above, I’ve written them inside a Concatenate function just so I could add some Text and then use the formulas. You may use differently.

In my case, the Formula goes like this –
Function(SharePointListName, ColumnName)

“Max” – Maximum Number in Score column of Scoreboard list


“Min” – Smallest Number in Score column of Scoreboard list

“Sum” = Total of all values in Score column of Scoreboard list

“Average” – Average of all values in Score column of Scoreboard list

“StdevP” – Standard Deviation arguments passed. Score column in this case

“VarP”-Variance of the arguments passed. Score column in this case

And that’s it! I tried to simply the explanation. However’s there much more to consider as well. Here’s the full documentation by Microsoft – https://docs.microsoft.com/en-us/powerapps/maker/canvas-apps/functions/function-aggregates
