Matrix table view in Custom visuals.

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"
              }
            }
          ]
        }
      }
    }
  ]
}
