Replicate class breaks for polyline layer

julian_svcs — Mon, 06 Mar 2023 22:30:13 GMT

I have a polyline feature layer and I would like to represent this layer using the equivalent of Standard Deviation in ArcGIS Pro.

I tried using class breaks as the renderer but this does not seem to work for line features.

Is there a way I can replicate this symbology in my JSAPI code?

Thanks very much for any assistance.

I was able to do this using the visualVariables property in a SimpleRenderer (I even threw in an offset for the lines):

var linkRenderer = new SimpleRenderer({ symbol: { type: "cim", // CIM Line Symbol data: { type: "CIMSymbolReference", symbol: { type: "CIMLineSymbol", symbolLayers: [{ type: "CIMSolidStroke", enable: true, color: [213,157,30,255], effects: [{ type: "CIMGeometricEffectOffset", offset: 3.0, method: "Rounded", option: "Fast" }] }] } } }, visualVariables: [ { type: "color", valueExpression: "$feature.voltr_"+ comparison_year + " - $feature.voltr_" + reference_year, stops: [ {value: 3000,color: "#ffa500"}, {value: 1,color: "#ffe3af"}, {value: 0,color: "white"}, {value: -1,color: "#e0e9f1"}, {value: -4400,color: "#4b6791"}, {value: -9900,color: "#1d1e22"} ] } ] });
