Select nested data keys from a dataset for plots

[captain-yoshi]

Here is my data:

Is there a way to select a child or nested children like the example below ? Or do I have to modify my dataset to only have only one level.

Plot.plot({
  marks: [
    Plot.boxY(data, {x: "query.request", y: "metrics.time"})
  ]
})

Yes, you can use a function accessor: {x: d => d.query.request, y: d => d.metrics.time}. Though I think in your case you may need to flatten your data, as the d.metrics.time is an array of samples and Plot.boxY will expect a single number. That might look like this…

Plot.plot({
  marks: [
    Plot.boxY(data.flatMap(d => d.metrics.time.map(t => ({request: d.query.request, time: t}))), {x: "request", y: "time"})
  ]
})

Super! Exactly what I wanted :)
