Hello,

how can I dynamically change the symbology on layers? I need to temporarily change the symbology for the selected layer.

Thanks

Ondra

Ondrej,

If the layer is GraphicsLayer or FeatureLayer then simply use .setRenderer(renderer) method to change the renderer.

FeatureLayer | API Reference | ArcGIS API for JavaScript

And if its ArcGISDynamicServiceMapLayer then you need to use .setLayerDrawingOptions() method.

Hi,

It would be nice to have a more detailed post of what you are asking, but I will attempt to guess...

If you are referring to changing the symbology on a publishing level (not a user having the ability to change the symoboloy)

Symbology can be changed on the Web Map level. 

Left click on the layer in the web Map >> Change Style
