Data reduction algorithm

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"
                            }
