trim vega-lite v3 中未使用的轴外部

Question

我怎样才能“trim”轴并摆脱[-101, 225] 两边的填充，特别是在 Vega-Lite v3 ?

Answer 1

您可以将 scale.domain 与 scale.nice=false 一起使用。这适用于 Vega-Lite v3 和 v4。例如：

{
  "$schema": "https://vega.github.io/schema/vega-lite/v3.4.0.json",
  "data": {
    "values": [
      {"label": "A", "value": -101},
      {"label": "B", "value": -50},
      {"label": "C", "value": 10},
      {"label": "D", "value": 116},
      {"label": "E", "value": 225}
    ]
  },
  "mark": "bar",
  "encoding": {
    "color": {"field": "label", "type": "nominal"},
    "x": {
      "field": "value",
      "scale": {"domain": [-101, 225], "nice": false},
      "type": "quantitative"
    },
    "y": {"field": "label", "type": "nominal"}
  }
}
