[英]Vega-lite display data label in grouped bar chart with multiple measures
我正在嘗試自定義下面的圖表以在條形圖中添加數據標簽。 你能幫忙嗎?
{
"$schema": "https://vega.github.io/schema/vega-lite/v5.json",
"data": {
"url": "data/movies.json"
},
"repeat": {"layer": ["Worldwide Gross", "US Gross"]},
"spec": {
"mark": "bar",
"encoding": {
"x": {
"field": "Major Genre",
"type": "nominal"
},
"y": {
"aggregate": "sum",
"field": {"repeat": "layer"},
"type": "quantitative",
"title": "Total Gross"
},
"color": {"datum": {"repeat": "layer"}, "title": "Gross",
"scale": {"range": ["#2a9d8f", "#e76f51"]}},
"xOffset": {"datum": {"repeat": "layer"}}
}
},
"config": {
"mark": {"invalid": null}
}
}

{"category": "A", "group": "z", "value": 0.9},
{"category": "B", "group": "x", "value": 0.7},
{"category": "B", "group": "y", "value": 0.2},
{"category": "B", "group": "z", "value": 1.1},
{"category": "C", "group": "x", "value": 0.6},
{"category": "C", "group": "y", "value": 0.1},
{"category": "C", "group": "z", "value": 0.2}
]
},
"encoding": {
"x": {"field": "category"},
"y": {"field": "value", "type": "quantitative"},
"xOffset": {"field": "group"},

},
"layer": [
