HeatmapRenderer on GraphicsLayer?

FabianoScardua — Mon, 26 Oct 2015 19:54:05 GMT

Is it possible assign a HeatmapRenderer to GraphicsLayer?

Like this:

var graphicLayer = new GraphicsLayer();

var heatmapRenderer = new HeatmapRenderer();

graphicLayer.setRenderer(heatmapRenderer);

map.addLayer(graphicLayer);

This code does not work properly.

Fabiano,

your heatmaprender needs to have Parameters, namely colors.

See here:HeatmapRenderer | API Reference | ArcGIS API for JavaScript

It's not work too.

When I use a FeatureLayer it's work , but with a GraphicsLayer it's not work.

var graphicLayer = new GraphicsLayer();

var heatmapRenderer = new HeatmapRenderer({
    colors: ["rgba(0, 0, 255, 0)","rgb(0, 0, 255)","rgb(255, 0, 255)", "rgb(255, 0, 0)"],
    blurRadius: 12,
    maxPixelIntensity: 250,
    minPixelIntensity: 10
});

graphicLayer.setRenderer(heatmapRenderer);

map.addLayer(graphicLayer);
