Set different opacity color fill for a single layer

Sai_AnandPeketi1 — Wed, 09 Aug 2017 12:04:50 GMT

Hello everyone,

I have a layer consist of 8 different categories for each category set a different color code and opacity in desktop and publish in the ArcGIS Server. It working fine in ArcGIS Online. Whenever I using the map services in ArcGIS API for JS the color code is fine, but the opacity is not working. It automatically set 0% transparency and 1 Opacity.

How can I set the different opacity for different categories in a single layer by the help of ArcGIS API for JS?

Thanks for the help.

For that you need to look at VisualVariables for renderers:
