I need to edit my web app so that I can change the attribute value defining the point symbols in a set of dynamic map service layers.  The points are symbolized by size and color.
I am not sure if this is possible? The closest example I have found is  here  - but in this example they are using class breaks only.  It appears I can also use a UniqueValueDefinition instead of the ClassBreaksDefinition used in the example as a parameter of the GenerateRendererTask, but in the API I only see a color ramp available (no change in size).  I would prefer to have defined colors and defined sizes, using the same values, with the ability to switch the defining attribute from the web interface, as in the example I included.   This is an existing application, so I need to maintain the use of dynamic map service layers (I can't use feature layers).

I see that a Unique Value renderer may be used for this, but that appears to only work for feature layers.


Any ideas, examples? Thanks in advance.
