Feature Cluster/Reduction - Render symbol color by size

ChrisSmith7 — Tue, 11 Jun 2019 19:28:26 GMT

Hello,

I understand featureReduction in v4 isn't yet on par with v3, so in v3, is it possible to render cluster colors by size? For example:

...rather than using Drawing/Rendering Info from the service:

...I'd like to have a renderer based on cluster size as determined by featureReduction. Something more like this:

Is this possible?

Thanks!

Inspecting the DOM, I can see there is a way I could loop over the radius vals and roll my own classification:

It would be preferable to take advantage of the API, though, if it's supported.

Ok, so I just created a function to loop the elements and assigned color based on three classes as a function of the cluster pixel size.

How did you manage to access the DOM elements in the canvas?
