[HACKYSTAT-DEV-L] Is it possible to allow multiple CategorySeries with the same name in CategoryDataModel?

Hi, Philip and Hongbing,

I am cleaning Core_Telemetry code and there is some workaround I really 
want to get rid of.

Current CategoryDataModel blows up when you add more than one 
CategorySeries with the same name. I have to use pretty arbitrary 
workaround by adding stars to category name in case of duplication.

I am not sure whether this is a restriction in JFreeChart or 
Core_Report. My understanding is this is caused by CategoryDataModel's 
internal use of Map and keys CategorySeries by name. If I am right, then 
it won't be hard to remove this restriction.

Thanks,

Cedric
