channels: {
year: {
value: {
transform: (data) => data.map((d) => d.year),
label: "My custom year label"
}
}
shorter, but maybe more arcane:
channels: {year: Object.assign((d) => d.year, {label: "My custom year label"})}
Note that it would be tempting to have the following—but it doesn’t work currently, since the label must be on the “value”:
channels: {year: {value: "year", label: "My custom year label"}}
