关于arcgis:arcgis-for-js动态空间featureLayer着色渲染-renderer设置

arcgis for js 等级着色

1. 依据公布的数据设置多种 symbol 款式

let less35 = {type: "simple-fill", // autocasts as new SimpleFillSymbol()
  color: "#38627a",
  style: "solid",
  outline: {
    width: 0.2,
    color: [255, 255, 255, 0.5]
  }
}
let less36 = {type: "simple-fill", // autocasts as new SimpleFillSymbol()
  color: "#FF66CC",
  style: "solid",
  outline: {
    width: 0.2,
    color: 'red'
  }
}

2. 创立一个 renderer, 设置要害 id（就是依据哪个字段进行分等级，我这里抉择的是 OBJECTID_1）, 接入之前创立款式并且依据值分等级

let render2 = {
  type:'class-breaks',
  field: "OBJECTID_1",
  classBreakInfos: [
    {
      minValue: 0,
      maxValue: 1000,
      symbol: less35,
      label: "< 35%" // label for symbol in legend
    },
    {
      minValue: 1000,
      maxValue: 2000000.3499,
      symbol: less36,
      label: "< 35%" // label for symbol in legend
    }
  ]
}

3. 于 featureLayer 中应用，不晓得的能够看我另外的文章

layerValue = new FeatureLayer({
    renderer:render2,
    id: "tempLyasdr",
    url:
      "http://*****:6080/arcgis/rest/services/*****/ShpDynamicWorkspace/MapServer/dynamicLayer",
    dynamicDataSource: {
      type: "data-layer",
      dataSource: {
        type: "table",
        workspaceId: "*****",
        // dataSourceName: "*****.shp",
      },
    },
});
