Custom Visual - How to get measure aggregation type

Hey guys,

 

I'm writing a custom matrix visual . The dataview has a matrix , when I get measures data(Values) , I need to know what type of aggregation measure is (sum, count , average , min ,max ).

 

How can I get measure aggregation type programmatically?

 

Here is my capabilities.json

{
        "dataRoles": [
            {
                "displayName": "Rows",
                "name": "rows",
                "kind": "Grouping"
            },
            {
                "displayName": "Columns",
                "name": "columns",
                "kind": "Grouping"
            },
            {
                "displayName": "Filters",
                "name": "filters",
                "kind": "Grouping"
            },
            {
                "displayName": "Values",
                "name": "measure",
                "kind": "Measure"
            }
        ],
        "dataViewMappings": [
            {
                "conditions": [
                    {

You can try using the solution described in my previous comments.

There's not good way to detect type but you might try to detect type by displayName.

I 'm trying to calculate matrix measure  totals/subtotals (sum,count,average,min,max) .

Is there a way configure my capabilities.json that will bring matrix measure  subtotals for row/column items?

 

Thanks in Advance .

No, subtotals are not supported yet. This feature is on our backlog (no ETA).

 

Just one more note, If you calculate totals in JS they might be a bit wrong as Power BI does not allow to get more than 1000 rows by default. This value can be configure via dataReductionAlgorithm but it can't be greater than 30000.
