How to do a group by with Choice field

[MihirY]

I am having a choice field called Cateogry which is having values as "Sancks,Electronics, Books" etc. Now i want to group by these SharePoint list items with category and show on Pie chart as well as in Gallery. Earlier I have maitained in single line of text for cateogry field. Then i have used below formula. Since I have changed column data type from Single line of text to choice, this formula will not work. This is giving error at column name and saying, expected values are Text. how to deal with this? Is it an issue or limitation?

AddColumns(GroupBy('Purchase Orders',"Category", "Group"), "TotalQuantity", Coalesce(Sum(Group, Quantity),0))

Hi MihirY,

Thanks for feedback.

Per my test, I found that a Choice column type is not supported in the GroupBy function.

Please consider to submit a request at PowerApps ideas Forum:
https://powerusers.microsoft.com/t5/PowerApps-Ideas/idb-p/PowerAppsIdeas

I will help and collect it on my side.

Best regards,

It is sad to know that Choice field is not supported for GroupBy function. Any workaround is there? 

One workaround i think is:

We can create one more field in the same list with single line of text and update the value with workflow as choice field value. Now use that field in groupby function inside powerapp. But this is too indirective way. What you think?

I have submitted an idea in power apps form for Choice field not supported in groupby function.

Workaround:
Use AddColumns to introduce a new field based on the Complex field then group by the new field.

e.g. if my choice field is Category 

Groupby(AddColumns(DataSourceName, "NewFieldName",Category.Value),"NewFieldName","GroupName")
