joinaggregate question

[jjwAmtelco]

This elixir code I have seems ok but does not produce a chart. I have commented out the line that causes the issue; The joinaggregate line.
it is not clear to me why that line causes a blank chart. My goal is to produce a chart like what is shown in the editor...not sure its a bug but can transform be used some other way?

`data = skill_stats

fit_bars = Enum.count(get_skills(skill_stats)) * 22

# will never be smaller than 200 but expand depending
# on data [ for each skill ] and overflow to a scroll
width = max(fit_bars - rem(fit_bars, 100), 200)

Vl.new(title: "Service Level By Skill", description: "")
|> Vl.data_from_values(data)
|> Vl.concat(
  [
    Vl.new(width: width, height: 200)
    |> Vl.encode_field(:x, "skill",
      type: :nominal,
      title: "",
      axis: [label_angle: -45, label_font_size: 15])


    |> Vl.encode_field(:y, "value",
      type: :quantitative,
      aggregate: :sum,
      stack: "normalize",
      title: "percentage of calls",
      axis: [format: ".0%"],
      sort: [field: "value"]
    )
    |> Vl.encode_field(:color, "series", scale: [scheme: "spectral"], legend: [orient: "left"])
    |> Vl.encode(:order, aggregate: "sum", field: "value")
    #|> Vl.transform(joinaggregate: "value", op: :sum, groupby: "skill", as: "TotalCount")
    |> Vl.transform(calculate: "datum.value/datum.TotalCount * 100", as: "PercentOfTotal")
    |> Vl.encode(:tooltip, [
      [field: "skill", type: :nominal],
      [field: "series", type: :nominal, title: "category"],
      [field: "value", type: :quantitative, title: "count"],
      [field: "sl_percentage", type: :quantitative, title: "Service Level %"],
      [field: "abandon_percentage", type: :quantitative, title: "abandon %"],
      [field: "PercentOfTotal", title: "% of Calls per skill", type: :quantitative, format: "0.2f"]
    ])
    |> Vl.mark(:bar)
  ],
  :horizontal
)
|> Vl.to_spec()
|> Jason.encode!()`

chart in editor

Do you get an error? Maybe it is joinAggregate, no?

[jjwAmtelco]

No error and no overflow menu to check the Jason. I can run the code without the line in it to ge the json if that is of any use… From: José Valim ***@***.***> Sent: Friday, February 3, 2023 4:01 PM To: livebook-dev/vega_lite ***@***.***> Cc: Joe Waldner ***@***.***>; Author ***@***.***> Subject: Re: [External] [livebook-dev/vega_lite] joinaggregate question (Issue #41) Do you get an error?

Open the Chart in the Vega Editor

this is the chart without the line, in the past when something is just wrong with the case it has still shown up in the editor...

[Jonatan Kłosko]

This would match the chart definition you have in the Vega Editor:

|> Vl.transform(
  joinaggregate: [[field: "value", op: :sum, as: "TotalCount"]],
  groupby: ["skill"]
)

Tried joinAggregate no joy

[jjwAmtelco]

That worked!!!!

I did not notice that the joinagreggate was a list in the json
Thanks
