Hi,
Is it in 3.16 possible to apply a HeatmapRenderer to a GraphicLayer?
I searched the discussion forum and only found that this was not working a while back (HeatmapRenderer on GraphicsLayer?) and a workaround using a custom DynamicMapServiceLayer for Heatmap.js (Heatmap layer as Graphics Layer? ).
I created a new GraphicLayer and set a HeatmapRenderer ...
var heatmapLayer = new GraphicsLayer({
id: "heatmap"
});
heatmapLayer.setRenderer(HeatmapRenderer)
map.addLayer(heatmapLayer);
... then added graphics (Points) to it with the symbol = null ...
var graphic = new Graphic(aggregation.geometry, null, aggregation.attributes, null);
heatmapLayer.add(graphic)
[...]
heatmapLayer.refresh();
... but the layer won't render this as a HeatMap. Any suggestions how this can work?
Thanks a lot!
Tom
