Hi,

I am trying to use your Multi Series Line Chart with Labels on Vega lite
My Configuration: ES/Kibana 6.4.3

Here is my configuration:

{
  "$schema": "https://vega.github.io/schema/vega-lite/v2.json",
  "data": {
    "url": {
      "%context%": true,
      "%timefield%": "cdate",
      "index": "index-*",
      "body": {
        "aggs": {
          "time_buckets": {
            "date_histogram": {
              "field": "cdate",
              "interval": {"%autointerval%": true},
              "extended_bounds": {
                "min": {"%timefilter%": "min"},
                "max": {"%timefilter%": "max"}
              },
              "min_doc_count": 0
            }
          }
        },
        "size": 1000
      }
    },
    "format": {"property": "aggregations.time_buckets.buckets"}
  },
  "width": 800,

  "layer": [
    {

      },
      "layer": [
        {"mark": "line"},
        {

            "opacity": {
              "condition": {"selection": "label", "value": 1},
              "value": 0
            }
          }
        }
      ]
    },
    {
      "transform": [{"filter": {"selection": "label"}}],
      "layer": [
        {
          "mark": {"type": "rule", "color": "gray"},
          "encoding": {"x": {"type": "temporal", "field": "cdate"}}
        },
        {
          "encoding": {
            "text": {"type": "quantitative", "field": "cons"},
            "x": {"type": "temporal", "field": "cdate"},
            "y": {"type": "quantitative", "field": "cons"}
          },
          "layer": [
            {
              "mark": {
                "type": "text",
                "stroke": "white",
                "strokeWidth": 2,
                "align": "left",
                "dx": 5,
                "dy": -5
              }
            },
            {
              "mark": {"type": "text", "align": "left", "dx": 5, "dy": -5},
              "encoding": {"fill": {"type": "nominal", "field": "area"}}
            }
          ]
        }
      ]
    }
  ]
}

However i do not see anything apart from the X & Y -axis. There are also no errors that i come across.
