Data reduction algorithm

Anonymous — Fri, 17 Jul 2020 11:25:18 GMT

Hi,

im working on custom visual that returns this error: "too many 'Task No' values" Not displaying all data. Filter the data or choose another field."

I tried to fix this according the data reduction algorithm: https://github.com/mvgaliev/PowerBI-visuals/blob/942d72065ec6703878249d32cb8df41a00827750/Capabilities/DataViewMappings.md

The error is due to "tasks".

so i tried this: (on capabilities.json)

"categorical": { "categories": { "select": [ { "for": { "in": "Task" } , "dataReductionAlgorithm": { "top": { "count": 30000 } } }, { "for": { "in": "Parent" } }, { "for": { "in": "StartDate" } }, { "for": { "in": "Resource" } } ] }, "values": { "group": { "by": "Legend", "select": [ { "for": { "in": "EndDate" } }, { "for": { "in": "Duration" } } ] } } }

But it seems to have no affect. I also tried to set property to "window" or "bottom" and reduce count.

solved:

In my case it was necessary to place it after select in "categories" and "values"

"categorical": { "categories": { "select": [ { "for": { "in": "Task" } }, { "for": { "in": "Parent" } }, { "for": { "in": "StartDate" } }, { "for": { "in": "Resource" } }, { "for": { "in": "ParentResource" } }, { "for": { "in": "ExtraInformation" } }, { "for": { "in": "Milestones" } } ], "dataReductionAlgorithm": { "top": { "count": 30000 } } }, "values": { "group": { "by": "Legend", "select": [ { "for": { "in": "EndDate" } }, { "for": { "in": "Duration" } }, { "for": { "in": "Completion" } } ], "dataReductionAlgorithm": { "top": { "count": 30000 } } } } }
