Ordering a feild (date) in simple Vega Data Table - kibana

Question

I have a simple text vega ata table which we use in Kibana, it works fine, but I'm trying to find a way to order the results based on the arrival date, code below:
{
$schema: https://vega.github.io/schema/vega/v3.json
config: {
title: {offset: 20, fontSize: 14, font: "Helvetica", anchor:"start"}
}
title: {
text: Departure Airport Arrival Time
}
background: white
width: 1200
height: 100
padding: {"left": 0, "top": 5, "right": 5, "bottom": 5}
autosize: {type: "pad"}
// Define the data source
data: [
{
name: source
url: {
// change "index" to the name of the index
index: myindex*
"%context%": true
body: {
size: "10"
}
}
format: {property: "hits.hits"}
transform: [
{
type: flatten
// change fields to the actual path for flight segment but keep _source as a prefix
fields: ["_source.Something.FlightSegment"]
as: ["val"]
}
{
type: formula
as: x_position
expr: width * 1 / 4
}
{type: "formula", as: "line_height", expr: "20"}
{
type: stack
groupby: ["x_position"]
field: line_height
as: ["y0", "y1"]
}
]
}
]
marks: [
{
type: text
from: {data: "source"}
interactive: true
encode: {
enter: {
x: {field: "x_position", offset: -250}
y: {field: "y0"}
y2: {field: "y1"}
align: {value: "right"}
text: {field: "val.DepartureAirportCode"}
font: {value: "Helvetica"}
fontSize: {value: 14}
}
}
}
{
type: text
from: {data: "source"}
interactive: true
encode: {
enter: {
x: {field: "x_position", offset: -150}
y: {field: "y0"}
y2: {field: "y1"}
align: {value: "left"}
text: {field: "val.ArrivalDateTime"}
font: {value: "Helvetica"}
fontSize: {value: 14}
}
}
}
]
}
This is the result here:
You can see that the results are returned, but are out of order. What I would like to do is order it by ArrivalDateTime.
My problem is that most tutorials I have seen are for actual graphs and not for just plain old text.
Really appreciate anyone helping me out here.

Answer 1

I was curious about this too so found Vega lite sort
Especially sort by encoding from another field will do the job.
