Graph Query getTicket Calculations

I got it with some trial and error.
Parameters input as JSON array and values used in report as $Name…

query q {getCustomReport(name:"Ticket Calculations",parameters:[{name:"TicketId",value:"55955"}])
{
    name
    tables {
      rows {
        cells
      } 
    }
  }
}

into

[Ticket Calculations:3,2]
>Calculation Type|Amount
{REPORT CALCULATION DETAILS:C.Type,C.CalculationAmount:T.Id=$TicketId}

gives desired result… ish;

{
  "data": {
    "getCustomReport": {
      "name": "Ticket Calculations",
      "tables": [
        {
          "rows": [

                "Loyalty Wet Discount",
                "-10.00"
              ]
            },
            {
              "cells": [
                "Loyalty Dry Discount",
                "-5.00"
              ]
            }
          ]
        }
      ]
    }
  },
  "errors": null
