HeatMapLayer based on points from FeatureLayer

Question

Hi All -

I'm trying to create a HeatMapLayer from points in a FeatureLayer.

How do i get the geometry from the FeatureLayer (e.g. 'MapPoints') so i can add them to the 'HeatMapPoints' point collection for the HeatMapLayer?

I have a query task set up on the FeatureLayer (which works) and i have 'returnGeometry' set to true. But I can't seem to figure out how to actually access that geometry information.

Thanks for any help you can offer!!

Hi,
This one helped me too, additionally i am wondering if we could add heat map for one of the attribute of data points instead of its density over a subsidiary. For e.g. drawing heat map for revenue from customer instead of number of customer distributed over the subsidiary.

I don't think you can do that out of the box but you can tweak the HeatMapLayer code which is public.
