GraphQL, name, id

[erlebacher]

I am making progress in creating a customized multi-line chart with Vega-lite (not Vega). I noticed that on the GraphQL page, that “name” and “id” are always available. If wanted to do a groupby by name, how would that be accomplished? Would I use datum.name? Would I have to use quotation marks, like "datum.name"? Any information would be appreciated. Thanks.

Hey @erlebacher, you can groupby within the UI itself by going to the following page:

If you want to edit the Vegalite script directly, you can use something similar to the following:

"transform": [
    {
      "calculate": "if('${field:groupKeys}' === ''  || datum['${field:groupKeys}'] === '', false, true)",
      "as": "grouped"
    },
    {
      "calculate": "if('${field:groupKeys}' === ''  || datum['${field:groupKeys}'] === '', datum.name, datum['${field:groupKeys}'])",
      "as": "newGroupKeys"
    },
    {
      "calculate": "if('${field:groupKeys}' === ''  || datum['${field:groupKeys}'] === '', datum.color, datum['${field:groupKeys}'])",
      "as": "color"
    },
  {
    "joinaggregate": [
      {
      "op" : "average",
      "field": "${field:y}",
      "as": "groupedY"
      }
    ],
    "groupby": ["${field:x}", "newGroupKeys", "color", "grouped"]
  }
]

Thanks! I will look into it.
