Jody Garnett - 13/Mar/06 01:56 AM We have added a new aggregation api for geotools 2.2., and are producing classifications using the color brewer module. The classification functions james is talking about work a little bit like the series of rules produces by the color brewer module, but they can be used as a single Expression. This would allows us to classify "color" of a PointSymbolizer by "severity", and classify size by probability.

Jody Garnett - 13/Mar/06 01:58 AM I am marking this as minor, because: 1. Application code could do this, our function api is open 2. Application code could produce rules (for a single classification) as done with the cbrewer module 3. Application code could produce a power set of rules to vary two attributes
