How to create Custom Renderer in JS?

Question

Hi all,

I must create a custom Renderer that combines classBreakRenderer and UniqueValueRenderer to symbolize special GraphicLayer.
How do I accomplish it? what is the synatx to do it?

I am totally stuck because I need to represent graphics according to classbreak values and uniqueValue attributes.

Very appreciate for any help

Can you guys please let me know, if you could achieve this. I did not find any way to do this.

I could implement custom renderer, by extending "esri.renderer.Renderer". And overriding "getSymbol(graphic)" function. We need to write code in "getSymbol" function to identify the symbol to be applied for the "graphic" passed as parameter. And we need to create object for this custom renderer and apply this on layer. This function would be internally called for each graphic and that graphic will be displayed with symbol returned by this function.

Were you able to achieve this?  I am trying to do the exact same thing i.e. have a map show different shapes based on unique values but also show different colors based on number of entities.

Thanks in advance!
