Unable to display points using Unique Value Renderer

ilyasmd — Tue, 27 Sep 2022 11:57:26 GMT

I am not able to display dots with different colors for specific points using unique value renderer below are the details:

I am creating a feature layer and adding it to my map, I call my backend api which provides me with few points with Lat and Long, below is the sample data(omitting few data fields for brevity):

Api data:-

apiData = [{ "EP_A_NUM": 1212,"W_NUM": 2, "W_EXPL_NAME": "ANBU_2", "W_PRIM_HID": "ANBU", "SV_LAT_CORD": 240732.6389,"SV_LON_CORD": 380810.2614},

{ "EP_A_NUM": 1313,"W_NUM": 3, "W_EXPL_NAME": "ANBU_3","W_PRIM_HID": "ANBU", "SV_LAT_CORD":240728.6681,"SV_LON_CORD":380809.5087}]

Feature layer creation source code:

new FeatureLayer({

source: apiData,

objectIdField: "EP_A_NUM",

renderer: {

type: "unique-value",

field: "W_EXPL_NAME",

defaultSymbol: { type: "simple-marker", color: "red" },

uniqueValueInfos: [ {

value: "ANBU_2",

symbol: {

type: "simple-marker",

color: "black"

}]

fields: [

{ alias: 'W_EXPL_NAME', name: 'W_EXPL_NAME', length: 255, type: 'string' },

{ alias: 'EP_A_NUM', name: 'EP_A_NUM', type: 'integer' },

{ alias: 'W_NUM', name: 'W_NUM', type: 'integer' },

{ alias: 'SV_LAT_CORD', name: 'SV_LAT_CORD', length: 255, type: 'double' },

{ alias: 'SV_LON_CORD', name: 'SV_LON_CORD', length: 255, type: 'double' },

]

geometryType: "point",

id: 'wells layer',

spatialReference: { wkid: 4326 },

});

view.map.layers.add(wellsLayer); //adding the newly created feature layer to my base map

Even if the data contains 'ANBU_2', all the dots are always displayed in red color, whereas one of the point is expected to be displayed in black color.

I am not able to understand where is the miss, please help.

Hard to tell from the partial code provided. Do you have a simple CodePen (or similar) showing the issue?

I have used projection service because of which this issue was being
raised. I was able to fix the issue.
Thanks
