Hi Team,
We are working on ArcGIS JS API 4.28 and using MapImageLayer and join-table with standalone table and join is working perfectly.
We are facing the issue in displaying the Label on this joined map image layer but label is not displaying.
I am sharing the code -
var queryString =
"SELECT id,name from test";
const layer = new MapImageLayer({
url: "https://sample/MapServer",
title: "United States Population",
sublayers: [
{
title: "Share of population with Norwegian Ancestry",
id: 0,
labelingInfo: [
{
labelExpression: "[name]",
labelPlacement: "always-horizontal",
symbol: {
type: "text", // autocasts as new TextSymbol()
color: [255, 255, 255, 0.7],
haloColor: [0, 0, 0, 0.7],
haloSize: 1,
font: {
size: 11,
},
},
},
],
opacity: 0.75,
source: {
type: "data-layer",
dataSource: {
type: "join-table",
leftTableSource: {
type: "map-layer",
mapLayerId: 0,
},
rightTableSource: {
type: "data-layer",
dataSource: {
type: "query-table",
workspaceId: "testworkspace",
query: queryString,
oidFields: "id",
},
},
leftTableKey: "name",
rightTableKey: "name",
joinType: "left-outer-join",
},
},
},
],
});
Now I want to know how to display the label on joined tables?? and also want to know which fields will be displayed(Map Layer or System Table).. what is the syntax.
