I have a set of data held in a backend database that I wish to render into a heatmap using esri. The data is dynamic based on users search and filters.
I'm creating the feature layer and applying the heatmap renderer but getting no luck with this, one thing I notice is that when I log the layer to the console the graphics geometry's are null whether this is the issue I'm not sure.
I've created a jsfiddle of where I am currently.
