Matrix table view in Custom visuals.

Sundar1606 — Thu, 30 Nov 2017 12:30:25 GMT

I'm trying to build a custom visual, there i need the data like what we have in tables. I drag two column into "Summize Category"(Category name) and one column into "Measure Data". In dataview array contains categorical in that categories has multiple column. But values showing for only first category. Is there anything i need to tweak in dataviewmapping.

The following json structure is data roles and Data View Mappings

{
  "dataRoles": [
    {
      "displayName": "Summize Category",
      "name": "myCategory",
      "kind": "Grouping"
    },
    {
      "displayName": "Measure Data",
      "name": "myMeasure",
      "kind": "Measure"
    }
  ],
  "dataViewMappings": [
    {
      "categorical": {
        "categories": {
          "for": {
            "in": "myCategory"
          },
          "dataReductionAlgorithm": {
            "top": {}
          }
        },
        "values": {
          "select": [
            {
              "bind": {
                "to": "myMeasure"
              }
            }
          ]
        }
      }
    }
  ]
}

Results of Data

"dataViews": [
    {
      "categorical": {
        "categories": {
          "0": {
            "source": {

I think it'd be better to use table or matrix data-mappings instead of categorical:

{
    "dataRoles": [
        {
            "displayName": "Summize Category",
            "name": "myCategory",
            "kind": "Grouping"
        },
        {
            "displayName": "Measure Data",
            "name": "myMeasure",
            "kind": "Measure"
        }
    ],
    "dataViewMappings": [
        {
            "table": {
                "rows": {
                    "select": [
                        {
                            "for": {
                                "in": "myCategory"
                            }
                        },
                        {
                            "for": {
                                "in": "myMeasure"
                            }
                        }
                    ]
                }
            }
        }
    ]
}
