Vega / Kibana Custom Visualization with multiple X axis parameters

I'm trying to archieve something like this : example, using kibana and/or Vega/Vega-lite.

The csv file I used to add the index to kibana was:

student1,90,80,85,95
student2,50,60,55,100
student3,40,70,50,60

At the moment I have this:

{
  "$schema": "https://vega.github.io/schema/vega-lite/v2.json",
  "data": {
    "url": {
      %context%: true,
      "index":"grades",
      "body":{
          "size":5
          "_source":["StudentName","test1","test2","test3","test4"]
        }
      },
      "format":{"property":"hits.hits"}
  },
  "mark": "line",
  "encoding": {
    "x": {"field": "_source.test1", "type": "quantitative"},
    "y": {"field": "_source.StudentName", "type": "nominal"}
  }
}

So my problem is trying to archieve what is on the picture. I know the "encoding" section of my Vega code isn't correct but I'm having problem finding a way of having multiple parameters in X-axis.

I think this : vega example would do the trick if i managed to replace the hardcoded values in data with the data from the kibana index. Is there any way I can use the "_source.fields" inside the "values" or is any option in encoding that I can use in order to archieve my result?

Thanks in advance.

Note: My end result most likely only have 1 student. But I want that the visualization to be updated in real-time, therefore the need to use the field.
