Is it possible to format the "proportion-facet" value from a groupZ transformation in a Plot.text mark?

I am able to display the values correctly on the stacked bars, but I haven't found a way yet to format the values correctly (25% instead of 0.25). I tried a few things that work in a different context, but to no avail.

See Notebook

Plot.plot({ color: { legend: true }, x: { percent: true }, marks: [ // Stacked bars with normalized proportions Plot.barX( carss, Plot.groupZ( { x: "proportion-facet" }, // Compute proportions for each brand within a year { z: "brand", fill: "brand", tip: true, inset: 1, fy: "year", offset: "normalize" } ) ), // Centered text labels inside bars Plot.textX( carss, Plot.stackX( Plot.groupZ( { x: "count", text: "proportion-facet" }, { z: "brand", fy: "year", offset: "normalize" } ) ) ) ] })

Yes, with the map transform:

Plot.map({text: (values) => values.map(d3.format(".0%"))},
    Plot.stackX(…………) 
)

That works, thanks for the quick reply!
