When you try to use the transformation inside a mark, like this:
data = pdata.name('table') do
url('data/groups.json')
end
facet_t = facet_transform.keys('category')
group_m = group_mark.from(data, facet_t) do
enter do
y { scale(cat_s).field('key') }
end
endBecause it is not properly adding the transformation new field to data, it generates this:
"marks": [{
"type": "group",
"from": { "data": "table" },
"properties": {
"enter": {
"y": { "field": "data.key", "scale": "cat"},
}
}
}],But it actually should be like this:
"marks": [{
"type": "group",
"from": { "data": "table" },
"properties": {
"enter": {
"y": { "field": "key", "scale": "cat"},
}
}
}],
