How i wish that Mapguide studio is capable of theming a layer such as "Unique Value",so that a unique color representation for each feature is rendered Also Graduated Color, with templates or more option for Color Ramps or Styles...even Chart rendering would be best....
There is no other option except for the Style Ramp Interpolation only.
This is pretty hard to manually assign different colors to features, say if you have hundreds to thousands...
Even from the 2007 till 2009 version of Mapguide studio, i didnt see it.
