Overlapping points in graphics layer - ArcGIS JSAPI

carlossibuet — Tue, 05 Apr 2016 14:54:55 GMT

I am displaying 911 incidents in a web application using ArcGIS javascript API. Each graphic is created dynamically and added to a graphics layer on the map. I am doing this because the incidents are not being stored in a esri layer or feature class, just a plain table with x,y coordinates. The problem is that there are many points that overlap either because they have the exact xy or they are close enough.

I would like to show an icon with a count when the points overlap or are too close. When the user clicks on the icon, the infowindow should page through the overlapping graphics. I am aware on the point clustering layer widget available, but that layer is very limited, for instance you can only represent a single graphic with one symbol. I would like to represent each graphic with a symbol based on an attribute.

Thanks

Carlos
