推荐答案

是的，您需要在color属性中将scale设置为null.

Yes, you need to set the scale to null in your color property.

"encoding": {
      "x": ...,
      "y": ...,
      "color": {
        "field": "color",
        "legend": null,
        "type":"nominal",
        "scale": null
      }
    }

要直接编码数据值，可以将scale属性设置为 空.

To directly encode the data value, the scale property can be set to null.
