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": [ { "rows": { "max": 0 }, "columns": { "max": 0 }, "measure": { "min": 1 } }, { "rows": { "min": 1 }, "columns": { "min": 0 }, "measure": { "min": 0 } }, { "rows": { "min": 0 }, "columns": { "min": 1 }, "measure": { "min": 0 } } ], "matrix": { "rows": { "select": [ { "for": { "in": "rows" } }, { "for": { "in": "filters" } } ], "dataReductionAlgorithm": { "top": { "count": 30000 } } }, "columns": { "for": { "in": "columns" }, "dataReductionAlgorithm": { "top": { "count": 10000 } } }, "values": { "select": [ { "bind": { "to": "measure" } } ] } } } ], "objects": { "total": { "displayName": "Show Total", "properties": { "columnTotal": { "displayName": "Column", "type": { "bool": true } }, "rowTotal": { "displayName": "Row", "type": { "bool": true } }, "columnGrandTotal": { "displayName": "Grand Column", "type": { "bool": true } }, "rowGrandTotal": { "displayName": "Grand Row", "type": { "bool": true } } } } } }
Is there any update on how to get measure aggregation type?
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.
